(a) Calculate e.m.f. of the following cell :
Given :
(b) and are two electrolytes. On dilution molar conductivity of increases times while that increases times. Which of the two is a weak electrolyte and why ?
(a)
Given :
E0cell = E0C - E0A
= 0.80 – (-0.76) = 1.56 V
Ecell = E0cell – 0.0591/n log [Zn+2]/[Ag+]2
= 1.47 V
(b) Y is weak electrolyte , as molar conductivity increases with dilution due to increase in degree of dissociation.
