JEE Main Chemistry question

Ionic solids are characterised by:

(A)Good conductivity in solid state
(B)High vapour pressure
(C)Low melting point
(D)Solubility in polar solventsCorrect

Answer: (D)

Solution

Ionic solids dissolve readily in polar solvents (like water) because the solvent's dipoles can stabilise the separated ions through ion–dipole interactions. In the solid state, ions are fixed in the lattice and cannot move freely, so ionic solids are poor conductors
