To prepare a soluble salt, we can react an acid with an insoluble base (hydroxide or oxide).
To prepare an insoluble salt, we can use precipitation method which is by mixing two solutions of soluble compound.
However, can I prepare an insoluble salt by reacting an acid with an insoluble base (hydroxide or oxide)?
1. Calcium hydroxide + Sulphuric acid
2. Lead (II) hydroxide + Sulphuric acid
3. Lead (II) hydroxide + Hydrochloric acid
