Common mistake
Excess Solid Misunderstanding
Students often think that adding an insoluble solid in excess is to ensure all the acid reacts, rather than to ensure that the solution is saturated and all the acid is neutralised.
Emphasize that the excess solid ensures that any unreacted acid is neutralised, and the remaining solid can be filtered out, leaving a pure salt solution.
