CLARK CELL Meaning and Definition

1. A Clark cell refers to a type of electrochemical cell that is commonly used as a reference cell to measure voltages in electrical circuits. Named after its inventor, Josiah Latimer Clark, the Clark cell is composed of a saturated solution of mercurous sulfate (Hg2SO4) in water, along with a small amount of mercurous sulfate crystals at the bottom of the cell. A glass tube filled with mercury is inserted into the solution, serving as an electrode.

   The Clark cell functions based on the electrochemical reactions occurring at its electrodes. The mercurous sulfate crystals act as the anode, undergoing oxidation to release sulfate ions (SO42-) and one electron (e-) per Hg2SO4 molecule. This electron released at the anode migrates through the external circuit, resulting in a measured voltage. Meanwhile, the mercury electrode in the solution functions as the cathode, where sulfate ions and an electron combine to form mercurous sulfate.

   The Clark cell is known for its stable and reproducible output voltage, making it ideal for use as a reference cell in various applications. Its voltage is assigned a constant, typically 1.432 volts when measured against the standard hydrogen electrode. The Clark cell's accuracy and precision allow it to serve as a reliable voltage reference, particularly in calibrating scientific instruments, such as voltmeters and potentiometers, and in industrial settings where voltage measurements are crucial.

Etymology of CLARK CELL

The word "Clark cell" is named after its inventor, Josiah Latimer Clark. Josiah Clark was a British scientist and engineer who developed the Clark cell in 1873. The cell is a type of standard reference cell used in electrochemistry for precision measurements of voltage. It consists of a mercury amalgam electrode, a zinc electrode, and a potassium chloride (KCl) solution, which acts as the electrolyte. The Clark cell allows for accurate and stable voltage measurements and has been widely used in scientific and industrial applications. The cell was named after Josiah Clark to honor his contributions to the field of electrochemistry.
