Question

Assertion

Lithium sulphate does not form alums.

Reason

$L{i}^{+}$ is too small to form a stable lattice required for double-salt/alum formation.

• A. Both the assertion and the reason are correct. The reason is the correct explanation for the assertion
• B. Both the assertion and the reason are correct. But the reason is not the correct explanation for the assertion
• C. Assertion is correct but the reason is incorrect
• D. Both the reason and the assertion are incorrect

Answer 1

The correct option is A

Both the assertion and the reason are correct. The reason is the correct explanation for the assertion

Lithium sulphate is soluble in water, going with the general trend of the group. The other alkali metals sometimes form double salts whereas $L{i}^{+}$ is too small to form a stable lattice required for double salts/alum.
