The lesser solubility of NaHCO_3 than Na_2CO_3 in water is mainly due – InterviewSolution

1.	The lesser solubility of NaHCO_3 than Na_2CO_3 in water is mainly due to
Answer» higher lattice energy DUE to smaller size of `HCO_3^-` ion smaller hydration energy fo larger `HCO_3^-` ion INTERMOLECULAR H-bonding intermolecular H-bonding between `NaHCO_3` molecules and water molecules of crystallisation. Solution :Lesser SOLUBILITY is due to extensive intermolecular H-bonding between bicarbonate IONS in `NaHCO_3`.
