`NH_4OH` is a weak electrolyte whose `lambda^@m` can be found using `lambda^@m` of `NH_4CI`, NaCI and NaOH or by using `lambda^@m` of `NH_4NO_3`, `KNO_3`, and KOH. Similarly of weak ele-ctrolyte `CH_3COOH` can be found using strong electrolytes. Give two sets of electrolytes which can be used to find `lambda^@m` of `CH_3COOH`.
