THE CHEMISTRY BETWEEN COCA-COLA AND MILK MIXTURE.
Coca-cola and milk mixture. Coca-cola, like many soft drinks, use a significant amount of Phosphoric acid(H3PO4) to impart an acidic taste while stifling the growth of molds and bacteria in the drink. When you add milk to coca-cola or any other drink with phosphoric acid, results into layers which form a sewer liquid at the top and a sandy gravel residue after adding the milk into it and kept for about 6hours. This is as a result of the phosphate ions from the phosphoric acid which binds with the calcuim molecules in the milk. Here is the chemical equation for the reaction. 3Ca + 2H3PO4---> Ca3(PO4)2 + 3H2 Result formed after kept for few hours. The resulting compound is Tricalciumphosphate (Ca3(PO4)2which is heavy combination of two phosphate ions and three calcium ions. That is why it sinks to the bottom. The hydrogen gas that is produced floats to the top of the cle...
