Please help me for a chemical reaction 🙏🏻

Question

What is the chemical reaction occurs when boiling a mixture of water , flour , sugar, baking soda and vinegar ( for making homemade glue ) ?

Answer 1

Vinegar is an acid (acetic acid) and this helps in the breakdown (hydrolysis) of the flour and sugar. The boiling water (heat) also is important for breaking the bonds in flour and sugar. So, what is happening is that the flour and sugar are "decomposing" or breaking down into their component part. Flour is mostly made of starch which is a polysaccharide made of lots of units of different kinds of sugar. This breaks down into smaller monosaccharides, disaccharides, etc. Sugar (table sugar) is sucrose is a disaccharide and is made up of glucose and fructose. When heated with vinegar it turns into the two monosaccharides, glucose and fructose. This is essentially what is happening chemically when you mix them all together and heat them. Not sure what the baking soda (sodium bicarbonate) is there for other than to maybe neutralize the acetic acid making carbon dioxide and water.
