Sodium carbonate is highly soluble in water, but magnesium carbonate is less soluble. Why? |
| Answer» Solution :Cation of group IA,`M^(+)` has one unit CHARGE, while that of IIA, `M^(2+)` has two UNITS charge. The GREATER the charge, the greater is the lattice energy. In the case of magnesium carbonate, lattice energy dominates hydration energy. HENCE, it is less soluble. | |
