Conductance of Electrolytic Solutions - Measurement of the Conductivity of Ionic Solutions

Give reasons:

On the basis of E° values, O₂ gas should be liberated at anode but it is Cl₂ gas which is liberated in the electrolysis of aqueous NaCl.

In an aqueous solution how does specific conductivity of electrolytes change with addition of water?

Assertion: For measuring resistance of an ionic solution an AC source is used.

Reason: Concentration of ionic solution will change if DC source is used.

Define conductivity for the solution of an electrolyte.

The decreasing order of electrical conductivity of the following aqueous solutions is:

1. 0.1 M Formic acid,
2. 0.1 M Acetic acid,
3. 0.1 M Benzoic acid.

Conductivity of an electrolytic solution depends on:

(i) nature of electrolyte.

(ii) concentration of electrolyte.

(iii) power of AC source.

(iv) distance between the electrodes.

The conductivity of 0.20 M solution of KCl at 298 K is 0.0248 S cm⁻¹. Calculate its molar conductivity.

The cell constant of a conductivity cell ______.
