Question

Given below are two statements : Statement I : For KI, molar conductivity increases steeply with dilution.\ Statement II : For carbonic acid, molar conductivity increases slowly with dilution.\ In the light of the above statements, choose the correct answer from the options given below:\

Professor PC Thomas Classes · Answer

(b) : Molar conductivity of KI increases slowly with dilution because of weaking of interionic attractions and increase in ionic mobilities. As carbonic acid is weak acid, with increase in dilution the ionisation increases, thus total number of ions increase. Hence, molar conductivity increases steeply.\
