Redox Reactions And Electrochemistry Ques 716

Question: Equivalent conductance of saturated BaSO4 is 400,Ω1,cm2equ1 and specific conductance is 8×105,Ω1,cm1 . Hence, Ksp of BaSO4 is

Options:

A) 4×108M2

B) 1×108M2

C) 2×104M2

D) 1×104M2

Show Answer

Answer:

Correct Answer: B

Solution:

[b] λ0(BaSO4)=1000×sp,.conductanceconc.,(Normality)

Normality =1000×8×105400 Molarity=Normality2=104M

Ksp=S2=(104)2=108M2
