This question is about the preparation of soluble salts.
Soluble salts can be prepared by reacting metal oxides with acids. Give one other type of substance that can react with an acid to form a soluble salt.
Iron(III) sulfate contains the ions Fe3+\text{Fe}^{3+}Fe3+ and SO42−\text{SO}_4^{2-}SO42−. Give the chemical formula of iron(III) sulfate.
Describe a method to make pure, dry crystals of zinc sulfate from an insoluble metal carbonate and a dilute acid.
