Interpretation Introduction

(b)

Interpretation:

The molarity of unknown H₂SO₄(aq) solution should be determined.

Concept introduction:

The quantity of electric charge associated with 1 mole of electrons is given by Faraday constant

1 mol e− = 96485 C

Electric charge is not measured directly, but electric current is measured. 1 A of electric current is the transfer of 1 C of charge per second (C/s).

Charge (C) = Current (C/s) × time (s)
