(a) Following reactions occur at cathode during the electrolysis of aqueous silver chloride solution:
Ag + ( aq ) + e − → Ag ( s ) E ∘ = + 0.80 V
H + ( aq ) + e − →
H 2 ( g ) E ∘ = 0.00 V
On the basis of their standard reduction electrode potential( E ∘ )
(b) Define limiting molar conductivity. Why conductivity of an electrolyte solution decreases with the decrease in concentration?
