Select the correct statement(s) about the solubility of LiF and CsI in water

Options

  1. ALiF is highly soluble due to high hydration enthalpy
  2. BLiF is sparingly soluble due to high lattice enthalpy
  3. CCsl is highly soluble due to low lattice enthalpy
  4. DCsl is sparingly soluble due to low hydration enthalpy

Correct answer

D. Csl is sparingly soluble due to low hydration enthalpy

Step-by-step solution

Answer (B, D) Both LiF and Csl are sparingly soluble due to high lattice energy of former and low hydration enthalpy of latter.
