. The increasing order of solubility is
A. LiHCO3 < KHCO3 < NaHCO3 B. NaHCO3 < KHCO3 < LiHCO3
C. KHCO3 < NaHCO3 < LiHCO3 D. LiHCO3 < NaHCO3 < KHCO3
Solubility of salt is function of lattice energy and hydration energy. For maximum solubility of salt, hydration energy should be high and lattice energy should be low.
