Suggest a way to determine `Lambda_m^@` value of water.

Text Solution

Verified by Experts

The molar conductance of water at infinite dilution can be obtainedfrom the molar condutances at infinite dilution of `NaOH, HCl` and `NaCl`.`NaCl`.`NaCl`.``beginarray/rdotLambda_m^0(H_2 O) doteq Lambda_m^0(NaOH)+Lambda_m^0(HCl) cdot quad-Lambda_m^0(NaCl) endarray``
