Name an element from Group-2 which forms an amphoteric oxide and a water soluble sulphate. |
|
Answer» SOLUTION :Beryllium is an element from group 2 which gives an amphoteric oxide Bed and water soluble SULPHATE`BeSO_(4)`. `Ba(OH)_(2) +2OH^(-) to [Ba(OH)_(4)]^(2-)` `Ba(OH)_(2)+2HCl +2H_(2)O to [Ba(OH)_(4)]Cl_(2)` `BeSO_(4)` is soluble in water due to highest HYDRATION energy. It is much more than lattice energy. |
