Answer 2

Answer:

In a lead acid battery, hydrogen is liberated at negative plates​.

Explanation:

• A lead acid battery has two plates- positive and negative.
• Whenever a lead acid battery is about to completely charge, hydrogen and oxygen gas is liberated at negative and positive plate respectively.
• This occurs when the current being given is more than the current required to remove the remaining amount of lead sulphate on the plates.
• This excess current leads to the ionization of the electrolyte's water.
• Hydrogen being lighter than air, escapes from the battery.
• As a result, Hydrogen is only released when the charging current exceeds the current resulting in electrolysis.
