MY and \[N{{Y}_{3}},\] two nearly insoluble salts, have the same \[{{K}_{sp}}\] values of \[6.2\times {{10}^{13}}\] at room temperature. Which statement would be true in regard to MY and \[N{{Y}_{3}}\]?                 [NEET - 2016]

A)  The molar solubilities of MY and \[N{{Y}_{3}}\] in water are identical.

B)  The molar solubility of MY in water is less than that of \[N{{Y}_{3}}\]

C)  The salts MY and \[N{{Y}_{3}}\] are more soluble in 0.5 M KY than in pure water.

D)  The addition of the salt of KY to solution of MY and \[N{{Y}_{3}}\] will have no effect on their solubilities.

Correct Answer: B

Solution :

[b]

molar solubility of NY3 is more than MY in  water.
