1.	For any sparingly soluble salt `[M(NH_(3))_(4)Br_(2)] H_(2)PO_(2)` Given: `lambda_(M(NH_(3))_(4)Br_(2)^(+))^(@) = 400 Sm^(2) - mol^(-1)`. `lambda_(H_(2)PO_(2)^(-))^(@) = 100 S-m^(2) -mol^(1)` Specific resistance of saturated `[M(NH_(3))_(4)Br_(2)] H_(2)PO_(2)` solution is `200 Omega-cm` If solubility product constant of the above salt is `10^(-x)`. What will be the value of `x`.
Answer» Correct Answer - 16 `^^_(m)^(oo) = K xx(1000)/(m) xx 10^(-6)` `500 = (1)/(200) xx (1000)/(5) xx 10^(-6)` `S = 10^(-8) mol//L` `K_(sp) = S^(2) = 10^(-16)`
