Question: How to use Arabic Gum? I had always used Canada Balsum to preserve specimens. Yet, now I need to use Gum Arabic. It is in powder form, I think. Does anyone have experience of using it.

Answer: Gum arabic can be almost completely dissolved in its own volume of water—a very unusual characteristic. I added the resulting solution to the pancake syrup, and in less than half a minute, the sugar crystals dissolved. Gum arabic is the hardened sap of the Acacia senegal tree, which is found in the swath of arid lands extending from Senegal on the west coast of Africa all the way to Pakistan and India. Just as Arabic numerals acquired their name because Europeans learned of them from the Arabs—who had picked them up from India—so too do we owe the name of gum arabic not so much to its origins, but to Europe’s early trading contacts with the Middle East. According to Sudanese sources, gum arabic was an article of commerce as early as the 12th century BC. It was collected in Nubia and exported north to Egypt for use in the preparation of inks, watercolors and dyes. Herodotus, writing in the fifth century BC, mentions its use in embalming in Egypt. In the ninth century of our era, the Arab physician Abu Zayd Hunayn ibn Ishaq al-Ibadi, writing in his Ten Treatises on the Eye, described gum arabic as an ingredient in poultices or eye compresses Gum arabic, a natural gum also called gum acacia, and chaar gund or char goond (in India), is a substance that is taken from two sub-Saharan species of the acacia tree, Acacia senegal and Acacia seyal. It is used primarily in the food industry as a stabilizer, but has had more varied uses in the past, including viscosity control in inks. Its E number is E414. Gum arabic is used as a binder for watercolor painting because it dissolves easily in water. Pigment of any color is suspended within the gum arabic in varying amounts, resulting in watercolor paint. Water acts as a vehicle or a diluent to thin the watercolor paint and helps to transfer the paint to a surface such as paper. When all moisture evaporates, the gum arabic binds the pigment to the paper surface. Photography The historical photography process of gum bichromate photography uses gum arabic to permanently bind pigments on paper. Ammonium or potassium dichromate is mixed with gum arabic and pigment to create a photographic emulsion, sensitive to ultraviolet light. Printmaking Gum arabic is also used to protect and etch an image in lithographic processes. Ink tends to fill into whitespace on photosensitive aluminium plates if they don't receive a layer of gum. In stone lithography the gum etch is used to etch the most subtle gray tones. Phosphoric acid is added in varying concentrations to the gum arabic to etch the darker tones up to dark blacks. Multiple layers of gum are used after the etching process to build up a protective barrier that ensures the ink does not fill into the whitespace of the image being printed. Pyrotechnics Gum arabic is also used as a water soluble binder in firework composition.[edit] Effect on surface tension in liquids Gum arabic reduces the surface tension of liquids, which leads to increased fizzing in carbonated beverages. This can be exploited in what is known as a Diet Coke and Mentos eruption. Gum arabic is a complex mixture of saccharides and glycoproteins, which gives it its most useful property: it is perfectly edible. Other substances have replaced it in situations where toxicity is not an issue, as the proportions of the various chemicals in gum arabic vary widely and make it unpredictable. Still, it remains an important ingredient in soft drink syrups, "hard" gummy candies like gumdrops, marshmallows, M & M's chocolate candies, and most notably, chewing gums. For artists it is the traditional binder used in watercolor paint, and is used in photography for gum printing. Pharmaceuticals and cosmetics also use the gum, and it is used as a binder in pyrotechnic compositions. It is an important ingredient in shoe polish. It is also used often as a lickable adhesive on postage stamps and cigarette papers. Printers employ it to stop oxidation of aluminium printing plates in the interval between processing of the plate and its use on a printing press. The substance is grown commercially throughout the Sahel from Senegal and Sudan to Somalia.

Question: Is there a difference between acacia fiber and gum arabic?

Answer: Roughly speaking, they are the same. Gum arabic, a natural gum also called gum acacia, is a substance that is taken from two sub-Saharan species of the acacia tree, Acacia senegal and Acacia seyal. It is used primarily in the food industry as a stabilizer, but has had more varied uses in the past, including viscosity control in inks. Its E number is E-414. The gum produced by the trees in question reseals the plant's bark in the event of damage - a process called gummosis. Gum arabic is a complex mixture of saccharides and glycoproteins, which gives it one of its most useful properties: it is perfectly edible. Other substances have replaced it in situations where toxicity is not an issue, as the proportions of the various chemicals in gum arabic vary widely and make its reliable performance troublesome. Still, it remains an important ingredient in soft drink syrups, "hard" gummy candies like gumdrops, and in marshmallows. For artists it is the traditional binder used in watercolor paint, and was used in photography for gum printing. Pharmaceuticals and cosmetics also use the gum, and it is used as a binder in pyrotechnic compositions. It is an important ingredient in shoe polish.

Question: chemical formula of gum arabic ( in Mentos) and Diet Coke + Mentos experiment? Can you tell me the chemical formula of gum arabic in Mentos ? Also, how to do the Rocket experiment of Diet Coke + Mentos ( like put Mentos into Diet Coke then throw it upside down on the ground, it would launch like a rocket ) Finally, how to measure how high does the bottle go Thank you

Answer: composition:A carbohydrate polymer, complex and highly branched. The central core or nucleus is D-Galactose and D-glucuronic acid (actually the calcium, magnesium and potassium salts) to which are attached sugars such as 1-arabinose and 1-rhamnose. Most plant products that are not simple sugars are highly complex and vary in composition from lot to lot. D-galactose--C6H12O6 . D--Glucuronic Acid --?? Talk to you physics teacher to ask how to make a simple surveyor transit and to learn the math to estimate the height by using a simple angle measuring technique. This is a standard teaching experiment. If you have a rocket club in town, they may have the tools and will show you how to do a height tracking.

Question: gum arabic printing safety? Gum arabic printing is a aphotographic process which uses water soluble gum arabic and a water color pigment. When potassium dichromate is added to the mix and allowed to dry the gum arabic is sensitive to light and the decomposition of the potassium dichromate by light renders the gum insoluble in water. I have several questions about the safe handling of chemicals. potassium dichromate is a potentiala cancer causing agent. Is this chemical too hazardous to use at home for experimenting with gum printing? If it is are there any other possible chemicals which might decompose on exposure to light and allow an image to form in gum by rendering it insoluble- either an acid or oxygen might work. Best Regards Jim

Answer: The best way to determine the safety / health hazards for any chemical you are handling is to obtain its MSDS (Material Safety Data Sheet). Chemical manufacturers are required by law to produce an MSDS for each of their products, so if a quick search on-line does not produce a copy of the MSDS, you can always contact the manufacturer or vendor. In this case, I did find an MSDS for gum arabic (acacia gum) and for potassium dichromate. The MSDS shows, among other things, the carcinogenic toxicity of the chemical, protective equipment needed to handle it, how to dispose of it, flammability, etc, etc. Check it out at the link below
