A no. of ionic compounds, e.g., AgCl, CaF₂, BaSO₄ are insoluable in water. This is because
Options
(a) ionic compounds do not dissolve in water
(b) water has a high dielectric constant
(c) water is not a good ionising solvent
(d) hese molecules have exceptionally high attractive forces in their lattice
Correct Answer:
hese molecules have exceptionally high attractive forces in their lattice
Explanation:
lonic compounds having higher lattice energy than hydration energy are insoluble in water.
