Step 1

Oxidation is the process that involved the loss of electrons and oxidized to cation.  Hence when a molecule loses an electron, that molecule is said to be oxidized.  Metals have tendency to lose electrons and form cation such as sodium oxidized to sodium ion.

All metals are arranged in the metal activity series according to their reactivity. The more reactive metal is placed above in the series and will be good reducing agent whereas less reactive metal is placed below in the series.

Step 2

According to Faraday's law of electrolysis:

Step 3

Current = 58.50 mA = 58.50 x 10-3A

Volume of hydrogen gas = 1.000 x 102 L

Temperature = 273 K

Pressure = 1.00 bar = 0.987 atm

Calculate mole of hydrogen gas:
