Sodium Ascorbate

Question: which is better vitamin c, sodium ascorbate or calcium ascorbate? i went to healthy options store, looking for sodium ascorbate, however the sales assistant replied that they dont carry sodium ascorbate only calcium ascorbate,and besides according to the sales staff, its bad for the heart for those with with cardio vascular problems, due to its sodium (salt) content? it is true?

Answer: All that excess sodium does is to put up the BP a bit. Actual vitamin C is Ascorbic acid. However it is the ascorbate ion which is the active principle. Sodium ascorbate ionizes immediately. Calcium is slower. Therapeutically all three are the same.

Question: Which is better? Sodium Ascorbate or Calcium Ascorbate? I heard that taking sodium ascorbate is bad for you because it will make kidney stones, and it is better to take calcium ascorbate. Is this true? Can you also recommend a good brand/name for calcium ascorbate?

Answer: Sorry that this won't be the help that you're looking for, but you will probably be better asking this in the medical section. In the mean time, try speaking to your pharmacist - they can often offer good quality advice, which is more likely to be accurate compared to the advice you'll get in Yahoo Answers!

Question: 11. Sodium ascorbate (NaHC6H6O6) the sodium salt of ascorbic acid, is used as an antioxidant in food products? Sodium ascorbate (NaHC6H6O6) the sodium salt of ascorbic acid, is used as an antioxidant in food products. A 0.15 mol/L solution of the ascorbate ion (HC6H6O6) has a pH of 8.65. calculate Kb for the ascorbate ion.

Answer: HC6H6O6 - + H2O <> HC6H6O6H + OH- pH = 8.65 pOH =5.35 [OH-] = 10^-5.35 = 0.00000447 M = [ HC6H6O6H ] [ C6H6O6- ] = 0.15 - 0.00000447 = 0.15 Kh = Kw / Ka = (0.00000447)^2 / 0.15 = 1.33x10^-10 1 x 10^-14 / Ka = 1.33 x10^-10 Ka = 7.51 x10^-5 Kb = Kw/Ka = 1.33 x10^-10

Question: Do ascorbic acid and sodium ascorbate have the same benefits seeing as they're both forms of vitamin C anyway?

Answer: Ascorbic acid is used to prevent and treat scurvy, a disease caused by a lack of vitamin C in the body. Mineral ascorbates are salts of ascorbic acid (aka vitamin C). They are powders manufactured by reacting ascorbic acid with mineral carbonates in aqueous solutions, venting the carbon dioxide, drying the reaction product, and then milling the dried product to the desired particle size. The choice of the mineral carbonates can be calcium carbonate, potassium carbonate, sodium bicarbonate, magnesium carbonate, or many other mineral forms. Ascorbates are highly reactive antioxidants used as food preservatives. Ascorbate salts may be better tolerated than the corresponding weakly acidic ascorbic acid.

Question: what are the disadvantages of sodium ascorbate?

Answer: NutriBiotic Sodium Ascorbate is manufactured by dissolving pharmaceutical grade ascorbic acid with sodium bicarbonate (derived from sea water). It is a fully reacted, truly buffered form of vitamin C. Sodium ascorbate has long been the vitamin C used to supplement many foods, intravenous infusions and by those desiring an economical, non-bitter, fully reacted non-acidic vitamin C product. The sodium in this product differs from common table salt in that it is not combined with chloride, the andquot;saltandquot; most often associated with hypertension. Each gram (1000 mg) of vitamin C activity from Nutribiotic Sodium Ascorbate provides only 120 mg of sodium

Question: if vitamin c has to kinds, ascorbic acid and sodium ascorbate, which is better? and why sodium ascorbate is seldom or never been widely used or recommended compared with the ascorbic acid which is commonly use??

Answer: Both Are Very Similar, One is the Acid, the Other the Salt of the Acid, Physiologically Essentially the Same. The Salt Will Be Much Less Acid.

Question: how does the sodium ascorbate form of vitamin c is formed?

Answer: The ascorbic acid is combined with sodium bicarb in a reactor then processed into powder. I used to make it in a factory.

Question: Is sodium ascorbate can really cure cancer like cervical cancer? is it ok if i take 8 capsules of sodium ascorbate everyday?

Answer: Its just a vitamin C and cannot cure any cancer and stop taking so much ascorbat.consult with DOC

Question: How does sodium ascorbate turn colored water into transparent? There was this product demonstration wherein the demonstrator poured iodine into water and when he added sodium ascorbate the water again turned white. I don't understand how color gets masked? is it masked or the chemical bonds of the staining color have been altered? It was suppose to excite us about the cleansing effect of a new vitamin c product, but on the contrary it made me skeptical. I mean, why does it have to turn my body liquids to crystal clear; is this a good demonstration of how effective the product is? 'Cause it sure made me wonder if it would only alter the natural chemistry of my bodily fluids. really helpful Timothy. But i have a hard time looking for the specific URL. the URL u gave me is a broad one.

Question: What is the pH of a solution that consists of 0.50 M ascorbic acid and 0.75 M sodium ascorbate? Ka= 6.8x 10^-5 23. What is the pH of a solution that consists of 0.50 M H2C6H6O6 (ascorbic acid) and 0.75 M NaHC6H6O6 (sodium ascorbate)? Ka = 6.8 × 10-5 A. 3.76 B. 3.99 C. 4.34 D. 4.57 E. 5.66 I think the answer is E because since there is more of a base the solution is more basic.

Answer: Use the Henderson-Hasselbalch equation- pH = pKa + log(A-/HA) pKa = -log(6.8x10^-5) = 4.167 pH = 4.167 + log(0.75/0.50) pH = 4.167 + 0.176 = 4.34 ANSWER: C

Question: Where can i buy Sodium Ascorbate in Canada? I need it for vitamin C, where can i buy it online in Canada? thanks =)

Answer: Sodium Ascorbate is a simple Buffered Vitamin C... it's only really needed over regular Vitamin C if you get an upset stomach when you take regular Vitamin C or if you have an issue with acidity. Either way, you should be able to find either Sodium Ascorbate or other mineral ascorbates (Calcium Ascorbate, Potassium Ascorbate, etc) in your local health food store. If you can't find any Buffered C locally, you may have to order it from somewhere else and have them ship it to you. There are many higher quality companies out there that have Buffered C products, are readily available and well priced... just make sure the company has a good rating with either the GMP (Good Manufacturing Practices) or USP (U.S. Pharmacopoeia), as those are the main quality assurance organizations (USP is for the U.S., GMP is for the U.S. and worldwide). As long as they have good quality, the ingredients will be virtually identical in the pill. A few of the top quality companies I've found (all of which are competitors, so shop around for the best price) are at http://www.swansonvitamins.com http://www.puritanspride.com and http://www.vitacost.com I'm not aware of any major distributor that sells a huge variety of products that is based in Canada, but it's definitely good to shop around, especially where shipping is concerned... just make sure they are reputable and have good quality. ;-) Good luck and I hope I helped!

Question: Buffer question, help!? A buffer solution is prepared by mixing 75.7 mL of 0.0678 M ascorbic acid with 82.8 mL of 0.0785 M sodium ascorbate. pH of this buffer is 4.20. Calculate the pH (to two decimal places) of the buffer solution after the addition of 0.699 g of sodium ascorbate (NaC6H7O6) to the buffer solution above.

Answer: moles ascorbic acid = 0.0757 L x 0.0678 M= 0.00513 moles ascorbate = 0.0828 L x 0.0785 = 0.00650 total volume = 0.1585 L concentration ascorbic acid = 0.00513 / 0.1585 = 0.0324 M concentration ascorbate 0.00650 / 0.1585 = 0.0410 M 4.20 = pKa + log 0.0410/ 0.0324 4.20 = pKa +0.102 pKa = 4.10 moles sodium ascorbate = 0.699/ 198.11 = 0.00353 total moles ascorbare = 0.00353 + 0.00650=0.0100 concentration ascorbate = 0.0100 / 0.1585 =0.0633 M pH = 4.10 + log 0.0633 / 0.0324 = 4.39

Question: Chem: Acidity or Bascity of Salt Solutions? Will 0.10 M aqueous solutions of the following salts be acidic , basic or neutral? ammonium sulfide ((NH4)2S) sodium chloride (NaCl) ammonium hydrogen sulfite (NH4HSO3) sodium ascorbate (Na2C6H6O6) ammonium cyanide (NH4CN) Thanks a lot B-Mar, and Zulu warrior especially for that detailed response. I understand how to answer the question a whole lot better now.

Answer: Let me just say this to start off, just because they are salts and there charges balance doesn't mean that they are neutral. Acidic substances produce H+ ions in a solution. Basic substances produce OH- substances in solution. Neutral substances don't produce either in solution. There is really know set way to do this, but what I did was compare the relative strenghths of the acid-base pair using a chart that compared the Ka's and Kb's of selected bases and acids. The larger the Ka the more acidic the acid, the larger the Kb the more basic the base. The first one has ions of NH4+ and S2-(aq). NH4+(aq) is a acid, it can donates one of its hydrogens. S2-(aq) is a base, it can accept hydrogen ions. NH4+(aq) is a weak acid because its Ka is on the low side and S2- is a strong base because its Kb is on the high side. A weak acid plus a strong base makes a weak base. The reaction proceeds: NH4+(aq) + S2-(aq) --> HS-(aq) + NH3(aq) Both HS-(aq) and NH3(aq) are weak bases, so (NH4)2S is basic. NaCl is neutral becuase it is made up of Na+(aq) the conjugate acid of a strong base (NaOH) and Cl-(aq) the conjugate base of a strong acid (HCl). For NH4HSO3: NH4+(aq) and HSO3-(aq) are both acids because both can donate hydrogen ions. You already know NH4+ is an acid but HSO3- can also donate one of its hydrogen ions. A weak acid plus a weak acid makes a weak acid, so NH4HSO3 is acidic. For Na2C6H6O6: Na+(aq) again is the conjugate acid of a strong base, so it is neutral. C6H6O62-(aq) is the conjugate base of a weak acid (H2C6H6O6), so it is a weak base. C6H6O62-(aq) has the ability to accept two hydrogens, so Na2C6H6O6(aq) is a weak base. The last one has ions of NH4+ and CN-(aq). NH4+(aq) is a acid, it can donates one of its hydrogens. CN-(aq) is a base, it can accept hydrogen ions. NH4+(aq) is a weak acid because its Ka is on the low side and CN- is a weak base because its Kb is on the low side. A weak acid plus a weak base makes a neutral solution, so NH4CN is neutral. (If you want to get technical with this one, CN-(aq) is a slightly stronger base than NH4+(aq) is an acid so it would be slightly basic. But for your question I think it would be ok to say its neutral.) The answers are: ammonium sulfide (NH4)2S Basic sodium chloride NaCl Neutral ammonium hydrogen sulfite NH4HSO3 Acidic sodium ascorbate Na2C6H6O6 Basic ammonium cyanide NH4CN Neutral Remember these rules: strong acid + strong base --> neutral solution weak acid + strong base --> weak base weak base + strong acid --> weak acid weak acid + weak base --> neutral solution
