Answer:
1. a) Crystalline hydrated salt lose their mass or moisture on exposure to the air and change into amorphous salt, the phenomenon is called efflorescence.
b) Two salts that x could be are gypsum (Caso4.H2O) and copper (II) sulfate (CuSO4.H2O).
Gypsum (Caso4.H2O) form anhydrite(CaSO4), when exposed to air and copper (II) sulfate (CuSO4.H2O) form a white layer of anhydrous copper (II) Sulfate when expose to sir.
2. a) Salt hydrolysis is defined as the ions from salts react with water and form either basic or an acidic solution.
b) Two examples of salts that produce alkaline solutions when dissolving in water are sodium bicarbonate (NaHCO3) and Calcium Carbonate (CaCO3).
