When sulfuric acid is mixed with nitric acid it frees the nitrating ions which attach to the cellulose to form nitrocellulose. Im try ing to fully understand the reaction so i can mix the acids in the perfect ratio. And know how much cotton to add. There have been two methods so far one that used equal amounts and one the use two times the amount of sulfuric acid. The second creating a more explosive form of nitrocellulose.
I want to beleive that as the nitric acid is consumed the sulfuric acid is regenerated.
