1.	The lesser solubility of `NaHCO_3` than `Na_2CO_3` in water is mainly due toA. higher lattice energy due to smaller size of `HCO_3^-` ionB. smaller hydration energy fo larger `HCO_3^-` ionC. intermolecular H-bondingD. intermolecular H-bonding between `NaHCO_3` molecules and water molecules of crystallisation.
Answer» Lesser solubility is due to extensive intermolecular H-bonding between bicarbonate ions in `NaHCO_3`.
