Which of the following correctly describes the products of the electrolysis of an aqueous solution of KI?

Given the following standard reduction potentials,

Hg₂²⁺(aq)  +  2 e^–    2 Hg (l)                                                          E° = +0.789 V

Hg₂Cl₂(s)  +  2 e^–    2 Hg (l)  +  2 Cl^-(aq)                                        E° = +0.271 V

determine K_sp for Hg₂Cl₂(s) at 25 °C.

Ni (s)│Ni²⁺ (aq) ║Cu²⁺ (aq)│Cu (s) cell.

Which of the following is false about a Voltaic cell?

For the redox reaction label: the anode, cathode, half-reactions occurring at each half-cell, direction of electron flow, and direction of neutral ions flow.

$Ni\(\left\)(s\(\right\))+Zn^{2+}\(\left\)(aq\(\right\))\(\rightarrow\) Ni^{2+}\(\left\)(aq\(\right\))+Zn\(\left\)(s\(\right\))$

The diagram that follows represents a molecular view of a process occurring at an electrode in a voltaic cell.

(b) Is the electrode the anode or cathode?
