Question
Molar conductance of BaCl2, H2SO4 and HCl at infinite dilutions are x1, x2 and x3 respectively.Equivalent conductance of BaSO4 at at infinite dilution will be:
Options
A.(x1 + x2 - x3)/2
B.x1 + x2 - 2x3
C.(x1 - x2 - x3)/2
D.(x1 + x2 - 2x3)/2
Solution
λm∞(BaSO4) =λBa2+∞ + λSO42+∞
= λm∞(BaCl2) + λm∞(H2SO4)- - 2λ(HCl)∞
= x1 + x2 - 2x3 ; λeo =
λm∞(BaSO4)
= λm∞(BaCl2) + λm∞(H2SO4)- - 2λ(HCl)∞
= x1 + x2 - 2x3 ; λeo =
λm∞(BaSO4)Create a free account to view solution
