The trends in properties of alkaline earth metal salts can be explained by using Fajan's rule. It is associated with incorporation of covalent character in ionic bond. It states that smaller cations form more covalent compound and ionic character explains the solubility, thermal stability hydrolysis and other properties of these salts. Some exceptions are also there and are explained by change in lattice energy.
Correct order of increasing thermal stability of alkaline earth metal sulphates is
Which salt does not show hydrolysis at all -
Options:
Answer:
Solution:
The correct answer is D.
Salts formed from a strong acid and a strong base do not undergo hydrolysis. Barium chloride () is formed from barium hydroxide (, a strong base) and hydrochloric acid (, a strong acid). Therefore, does not hydrolyze. The other options are salts of strong acids and weak bases, which do hydrolyze.
