When the same quantity of electricity was passed through a dilute solution of sodium hydroxide and through a molten solution of lead bromide, 0.050 mol of lead was produced. what amount (in mol) of hydrogen gas was evolved

0.050 moles of hydrogen gas are liberated when a given quantity of charge liberates 0.050 moles of lead.

What amount in moles of hydrogen will be produced?

The amount in moles of hydrogen produced when the same quantity of electricity is passed through different electrolytes is inversely proportional to the charge on the ions.

The charge on the Lead ion is +2.

The charge on the hydrogen ion is +1.

2 atoms of hydrogen gives one molecule of hydrogen gas.

Hence, equal charge liberates equal amounts in moles of lead and hydrogen gas.

Therefore, 0.050 moles of hydrogen gas are liberated when a given quantity of charge liberates 0.050 moles of lead.
