Question

When an electric current is allowed to pass through a dilute sulfuric acid solution, hydrogen gas is evolved at the cathode and oxygen gas at the anode. What volumes of gases, measured at 1 atm and 273.15 K, will be obtained at the electrodes when 1.5 A of current is passed through the solution for 2 hours?

Answer 1

The formula to calculate the equivalents of electric current passed $Q$  is calculated as follows:

$Q=\frac{(i)(t)}{96500}$

Here,

$Q$ is the electric current passed.

$i$ is the current passed.

$t$ is the time.

$Q=\frac{(1.5)(2)}{96500}=3.11×10^{-5}$
