Paper: CSIR NET June 2017 · Subject: Physical Chemistry · Chapter: Electrochemistry · Topic: Nernst Cells · Marks: 2 · Difficulty: Medium
A solution of $\mathrm{Fe3+}$ is titrated potentiometrically using $\mathrm{Ce^{3+}}$ solution at 25°C. The emf (in V) of the redox system thus formed when, (i) 50 % of $\mathrm{Fe^{3+}}$ and (ii) 80% of $\mathrm{Fe^{3+}}$ are titrated, would respectively be (Given $E^\circ_{\mathrm{Fe^{3+}Fe^{2+}}} = 0.77\ \mathrm{V}$, log 2 = 0.301)
(a)0.734 and 0.77
(b)0.77 and 0.385
(c)0.77 and 0.734
(d)0.385 and 0.367
