What is the % dissociation of CH_(3)COOH, if equivalent conductivity at this dilution and at infinite dilution are 148 and 398 S cm^(2)//mol respectively

Answer»

`37.18%`
`47%`
`48.78%`
`10.8%`

SOLUTION :Degree of dissociation, `alpha`
`=("Equivalent conductance at concentration C")/("Equivalent conductance at INFINITE dilution")`
`=(148)/(398)=0.3718`
i.e., `CH_(3)COOH` is 37.18% DISSOCIATED.
