Answer» Solution :Double salts are those compounds which LOSE their identities in solutions and BREAK down into SIMPLE ions and exist in crystalline state. Example: Double salts like Potash ALUM `(K_2SO_4. AI_2 (SO_4)_3.2H_2O)` in aq. solution break down into `K^+, AI^3+, SO_4`. ions where they lose their identity. `K_2SO_4.AI_2(SO_4)_3. 24H_2OrarrK^(+)+2AI^(3+)+4SO_4^(=)+24H_2O` |
