Consider the following two statements: Statement I: No alkaline earth metal hydroxide is soluble in alkali. Statement II: The solubility of alkaline earth metal hydroxides in water rises on moving down the group. Select the most appropriate option in light of these statements.

1. Statement I is correct but Statement II is incorrect.
2. Statement I is incorrect but Statement II is correct.
3. Statement I and Statement II both are incorrect.
4. Statement I and Statement II both are correct.

Correct answer: Statement I is incorrect but Statement II is correct.

Solution

Be(OH)2 is amphoteric and does dissolve in alkali, so Statement I is incorrect; solubility of group 2 hydroxides increases down the group (Mg(OH)2 < Ca(OH)2 <... < Ba(OH)2), so Statement II is correct.
