Question

Amongst the following hydroxide, the one which has the lowest value of solubility product ( K s p ) at ordinary temperature (about 25 ° C ) is, M g ( O H ) 2, C a ( O H ) 2, S r ( O H ) 2, B e ( O H ) 2

MARKS App · Accepted Answer

The solubility of hydroxides of group 2 elements increases on moving down the group. B e ( O H ) 2 has minimum solubility in water. The lesser the solubility of the hydroxides, the smaller will be is solubility product. Hence, B e ( O H ) 2 has the lowest solubility product amongst the group 2 hydroxides.
