Answer» insouble `MgCO_(3)` by adding `Na_(2)CO_(3)` insouble `MG(OH)_(2)` by adding `Ca(OH)_(2)` insouble in `MgSO_(4)` by adding `Na_(2)SO_(4)` insouble `MgCI_(2)` By adding NaCI Solution :By the addition of `Ca(OH)_(2)` which is strong base to `Mg(OH)_(2) , its IONIC proiduct (Kip) INCREASES than the solubility product (Ksp) and precipitation takes place
