Answer on Inorganic Chemistry Question for Melissa

Question #6149
An aspirin product on the market claims to use magnesium hydroxide, Mg(OH)2, as a buffering agent. How could you verify whether magnesium ions are present?
Expert's answer
1. You need add some acid (HCl) to aspirinem(if Mg(OH)2 is present it must react with acid)
Mg(OH)2 + 2HCl = MgCl2 + 2H2O
2. Than we need add Na2HPO4
MgCl2 + Na2HPO4 = 2NaCl + MgHPO4 (it precipitates)
precipitate should be white and crystalline

Also Mg2+ reacted with Titanium yellow, C28H19N5Na2O6S4,giving red precipitate.
