1.	If the salt M_(2)X, QY_(2) and PZ_(3) have the same solubilities, their K_(sp) values are related as
Answer» `K_(sp) (M_(2)X) = K_(sp) (Q Y_(2)) lt K_(sp) (PZ_(3))` `K_(sp) (M_(2)X) gt K_(sp) (Q Y_(2)) = K_(sp) (PZ_(3))` `K_(sp) (M_(2)X) lt K_(sp) (Q Y_(2)) =K_(sp) (PZ_(3))` `K_(sp) (M_(2)X) gtK_(sp) (Q Y_(2)) gtK_(sp) (PZ_(3))` Solution :`M_(2)X and QY_(2)` are SALTS of the TYPE `A_(2)B` for which `K_(sp) = 4 S^(3)`. If S is same, `K_(sp)` will be equal. For `PZ_(3) , K_(sp) = S(3S)^(3)=27S^(4), ` i.e., much higher. Hence, (a) is the correct OPTION.
