`NH_4OH` is a weak electrölyte whose equivalent conductance can be found using the conductance of infinite dilution of `NH_4 Cl, NaCl` and `NaOH`. weak electrolyte `CH_3` COOH can-be found using strong electrolytes: 1. Give two sets of electrolytès which can be used to find the conductance of `CH_3 COOH`. 2. Which law is applied in the above measurement? Also explain the law. 3. Apply the law in the determination of equivalent conductance of CH_3COOH using any of, the sets you suggested.

Explanation

1. a. `CH_3 COONa, NaCl` and `HCl`
b. `CH_3 COOK . KNO_3` and `HNO_3`
2. Kohtrausch.s law. Statement of law.( See page oo. 84 )
3. `lambda eq CH_3 COONa+lambda eq HCl-`
`(lambda_eq^alpha CH , COO+lambda eq^ .Na^*).`
``
=lambda_eq^alpha CH_3^circ COO+lambda_eq^alpha H^+
