314967 The solubility of PbCl2 in water is S mol L−1 and its solubility product is Ksp. The relation between Ksp and S is represented as S=Kspx3. The value of x is ____ .
PbCl2(S)⇌Pb2+(S)+2Cl−(S)Ksp=[Pb2+][Cl−]2=S×(2S)2=4S3S=Kp43∴Value of x=4
314968 mole of BaCO3 are soluble in 1 L, then x is related to its solubility product by the expression
BaCO3→Ba2++CO32−If solubility = xKsp=x2⇒x=Ksp
314973 The solubility of AgCl in it's solution is 1.25×10−5moldm−3. What is the solubility product of AgCl ?
AgCl(s) ⇌Ag(aq) ++Cl(aq) −It is AB type of salt∴Ksp=S2=(1.25×10−5)2=1.56×10−10
314974 For the electrolyte of type A2B solubility product is Ksp. Then its solubility is
The relationship between KSP and S of salt Ax By is xxyy Sx+y.For A2B,KSP = (22)(11)S2 + 1 = 4S3
