Sample questions

Question 1

A galvanic cell consists of a \ce{Zn/Zn^{2+}} half-cell and a \ce{Cu/Cu^{2+}} half-cell. If the standard electrode potentials are \text{E}^\circ_{\text{Zn}^{2+}/\text{Zn}} = -0.76 \text{ V} and \text{E}^\circ_{\text{Cu}^{2+}/\text{Cu}} = +0.34 \text{ V}, what is the standard cell potential ( \text{E}^\circ_{\text{cell}}) for this cell?

Question 2

The standard electrode potential for \ce{Zn^{2+}/Zn} is -0.76 V and for \ce{Cu^{2+}/Cu} is +0.34 V. The standard EMF of the cell represented by \ce{Zn|Zn^{2+}||Cu^{2+}|Cu} is:

Question 3

Assertion (A): On electrolysis of aqueous NaCl solution, \ce{H2} is liberated at the cathode. Reason (R): The standard reduction potential of water (\ce{-0.83 V}) is less negative than that of \ce{Na+} (\ce{-2.71 V}).
