Provide an example of the amount of substance and current in electrolysis.

In electrolysis, the amount of substance and current are important factors.

Electrolysis is a process that involves the use of an electric current to drive a non-spontaneous chemical reaction. The amount of substance, also known as the quantity of charge, is measured in coulombs (C). This is the amount of electric charge that passes through a conductor in one second when a current of one ampere is flowing. The amount of substance is directly proportional to the current, so the more current that flows, the greater the amount of substance that is produced.

The current is the flow of electric charge through a conductor, measured in amperes (A). In electrolysis, the current is used to drive the chemical reaction by providing the energy needed to break the bonds between the atoms or molecules in the substance being electrolyzed. The amount of current required depends on the nature of the substance being electrolyzed and the desired rate of reaction. The greater the current, the faster the reaction will proceed.

For example, in the electrolysis of water, the amount of substance produced is directly proportional to the current. If a current of 1 ampere is passed through water for one second, then 1 coulomb of charge will have passed through the water, producing 0.0112 grams of hydrogen gas and 0.056 grams of oxygen gas. If the current is increased to 2 amperes, then the amount of substance produced will be doubled. Therefore, the amount of substance and current are important factors in electrolysis.
