Question

QUESTION 10 In cyclic voltammetry, the current is measured versus applied potential as the potential is swept from an initial value to a new value and then back to the initial value. This is called a _ waveform A. Square wave O B. Linear OC. Pulse OD. Triangular O E. Cycle

Answer 1

10. This is called triangular wafeform.

11. In cyclic voltammetry, the cathodic peak current is Ipc, the anodic peak current is Ipa, The cathodic peak potential is Epa, and anodic peak potential is Epa. The correct option is A.

12. The relationship between Epc, Epa and number of electrons n are given by

Epc - Epa = 57/n mv

Here n = 2 since two electrons are exchanged

Epc - Epa = 57/2 mv = 28.5 mv

The correct option is B.
