Faradic Current given Residual Current Solution

STEP 0: Pre-Calculation Summary

Formula Used

Faradic Current = Residual Current-Condenser Current
i_f = i_r-i_c
This formula uses 3 Variables

Variables Used

Faradic Current - (Measured in Ampere) - Faradic Current is defined as the current formed due to the traces of impurities.
Residual Current - (Measured in Ampere) - Residual Current is defined as the current that flows in the absence of the depolarizer (i.e. due to the supporting electrolyte).
Condenser Current - (Measured in Ampere) - Condenser Current is defined as the current due to the formation of Helmholtz double layer at the mercury surface.

STEP 1: Convert Input(s) to Base Unit

Residual Current: 10 Ampere --> 10 Ampere No Conversion Required
Condenser Current: 7 Ampere --> 7 Ampere No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

i_f = i_r-i_c --> 10-7

Evaluating ... ...

i_f = 3

STEP 3: Convert Result to Output's Unit

3 Ampere --> No Conversion Required

FINAL ANSWER

3 Ampere <-- Faradic Current

How does Rotating Platinum Electrode work ?

Rotating platinum electrode is used as an indicator electrode. To the analyte solution supporting
electrolyte like KCl is added i.e., 50-100 times of sample concentration. Pure nitrogen gas is
bubbled through the solution to expel out the dissolved oxygen. Potential is applied across the electrodes and titration is started. A graph is plotted between the volume of solution added v/s diffusion current and end point is detected.
