Solution

The correct option is B

High and high


Explanation for correct answer:

(B) High and high

  1. The solubility of 2nd group elements depends on their hydration energy which decreases down the group.
  2. So, the solubility also decreases down the group.
  3. Be and Mg are 2nd and 3rd group elements hence the solubility of their sulphates is high.

Explanation for incorrect options:

(A) High and poor

As Be and Mg are 2nd and 3rd group elements of group 2 so the solubility of their sulphates cannot be high and poor.

(C) Poor and poor

As Be and Mg are 2nd and 3rd group elements of group 2 so the solubility of their sulphates cannot be poor because solubility decrease down the group.

(D) Poor and high

As Be and Mg are 2nd and 3rd group elements of group 2 so the solubility of their sulphates cannot be poor and high because solubility decrease down the group.

Hence, option B is correct, as the solubility of BeSO4and MgSO4 in water is high.
