Coke Zero Sugar has slightly less sodium (25 mg in a 12-ounce serving compared to 40 mg per can of Diet Coke). Polyurethane resists degradation to a long list of chemicals. The molarity of phosphoric acid is then calculated by dividing the number of moles of phosphoric acid by the volume of the Cola used in the. The same thing happens if you drop it in a bottle of "Coke", which has citric acid, phosphoric acid, carbonic acid and other things in it for flavor. The main acids lurking in beverages are phosphoric acid and citric acid. Conclusions. Phosphoric acid is corrosive; however, acid concentration in soft drinks is even lower compared to that in lemonade or orange juice. It is a mineral acid that contains three atoms of hydrogen, one atom of phosphorus, and four atoms of oxygen. look down at cross on paper paper solution turns from colourless to cloudy sodium thiosulfate and hydrochloric acid cross on paper view looking down Initially the cross was clearly.

In this battery, a fraction of phosphoric acid (${\rm H_3PO_4}$) in the Coke disassociates into phosphate ions (${\rm PO_4^{3-}}$) and hydrogen ions (${\rm H^+}$). Phosphoric acid, also called orthophosphoric acid, (H 3 PO 4), the most important oxygen acid of phosphorus, used to make phosphate salts for fertilizers. Sulfuric, phosphoric, urea-sulfuric, or acetic acid can be used. Coca Cola can hardly be used as a substitute for phosphoric acid because it supposedly "contains phosphoric acid".
