The ionic half-equation for the formation of hydrogen at the negative electrode during the electrolysis of dilute hydrochloric acid is:
2H++2e−→H2 2\text{H}^+ + 2\text{e}^- \rightarrow \text{H}_2 2H++2e−→H2In one experiment, a charge of 0.0350 faraday0.0350\text{ faraday}0.0350 faraday is passed through the solution.
Calculate the amount, in moles, of hydrogen formed.
Calculate the volume of hydrogen formed at room temperature and pressure (rtp). [The molar volume of a gas is 24 dm324\text{ dm}^324 dm3 at rtp.] Give the unit in your answer.
