Question

The solubility of metal halides depends on their
nature, lattice enthalpy and hydration enthalpy
of the individual ions. Amongst fluorides of alkali
metals, the lowest solubility of LiF in water is
due to
(a) Ionic nature of lithium fluoride
(b) High lattice enthalpy
(c) High hydration enthalpy for lithium ion.
(d) Low ionisation enthalpy of lithium atom

Answer 1

Answer:

nature, lattice enthalpy and hydration enthalpy

of the individual ions. Amongst fluorides of alkali

metals, the lowest solubility of LiF in wate

(d) Low ionisation enthalpy of lithium atom

Answer 2

Answer:

B. HIGH LATTICE ENTHALPY

Hey MATE ...✋✋✋

HERE IS YOUR ANSWER....,

LOWEST SOLUBILITY OF LITHIUM FLOURIDE IS DUE TO HIGH LATTICE ENTHALPY WHICH IS HIGHER THAN HYDROGEN ENTHALPY. HENCE , THE DISSOCIATION

OF LI--F Bond BECAMES DIFFICULT.
