Common mistake
Misidentifying the solid reactant as the salt
Students write the insoluble solid (e.g. ZnS) as the product of the soluble salt preparation, rather than recognising it as the reactant that is added in excess
Explain that in a soluble salt preparation the insoluble solid is the reactant that reacts with the acid to form the soluble salt and a gas; the product is the soluble salt, not the solid that was added.
