How much hydrogen will liberate if 1F Electricity is passed through acidified water?

When 1 Faraday (1 F) of electricity is passed through acidified water, it liberates approximately 0.5 moles of hydrogen gas. This is based on Faraday's laws of electrolysis, where 1 Faraday is equivalent to the charge required to produce 1 mole of a monovalent ion. Since the electrolysis of water produces hydrogen gas at the cathode (2H⁺ + 2e⁻ → H₂), 1 F will result in the production of 1 mole of H₂, but since it is produced from 2 moles of electrons, it corresponds to 0.5 moles of hydrogen gas being liberated.
