Difference in pKa Values
Molar conductivity of a weak acid HQ of concentration 0.18 M was found to be 1/30 of the molar conductivity of another weak acid HZ with concentration of 0.02 of M. If 
happened to be equal with 
, the the difference of the pKa values of the two weak acids (pKa(HQ)–pKa(HZ)) is _______ (Nearest integer).
[Given : degree of dissociation (α) << 1 for both weak acids, λ° : limiting molar conductivity of ions]
