Master the Chloride Coulometer

• A chloride coulometer uses Faraday's law to measure the quantity of electricity used in an electrochemical system.
• The quantity of electricity is measured in coulombs, and a current of 1 ampere constitutes 1 coulomb of electricity flowing per minute.
• The number of equivalent weights of reactant oxidized or reduced depends on the duration of the current if the current is constant.
• In the chloride coulometer, Ag+ ions are generated by passing a direct current across a pair of silver electrodes in a conducting solution containing the sample to be assayed for chloride.
• The Ag+ ions combine with chloride to form insoluble silver chloride, which is removed from the solution.
• The endpoint of the titration is indicated by an increase in conductivity of the solution.
• Amperometry is used to measure the increase in conductivity.
• The chloride coulometer is used to measure the amount of chloride in a sample.
• The method is accurate and precise.
• The coulometer is widely used in analytical chemistry.
