313656
If \({\rm{N}}{{\rm{a}}^{\rm{ + }}}\) ion is larger than \({\rm{M}}{{\rm{g}}^{{\rm{2 + }}}}\) ion, and \({{\rm{S}}^{{\rm{2 - }}}}\) ion is larger than \({\rm{C}}{{\rm{l}}^{\rm{ - }}}\) ion, which of the following will be less soluble in water?
1 \({\rm{NaCl}}\)
2 \({\rm{N}}{{\rm{a}}_{\rm{2}}}{\rm{S}}\)
3 \({\rm{MgC}}{{\rm{l}}_{\rm{2}}}\)
4 \({\rm{MgS}}\)
Explanation:
MgS is more covalent, so less soluble

Solubility of alkali metal fluorides increases down the group. Select correct explanation for given statement
1 Hydration energy increases and lattice energy decreases down the group.
2 Both energy decreases down the group but decrease in hydration energy is rapid.
3 Both energy decreases down the group but decrease in lattice energy is rapid.
4 Both energy increases down the group but increase in hydration energy is rapid.
Explanation:
Although both hydration and lattice energies of alkali metal fluorides decrease down the group, hydration energy dominates over lattice energy, therefore, solubility increases down the group.

Which of the following is not a correct statement about an ionic compound?
1 The higher the temperature, the more is the solubility.
2 The higher the dielectric constant of the solvent, the more is the solubility.
3 The higher the dipole moment of the solvent, the more is the solubility.
4 The higher the lattice energy, the more is the solubility.
