The Normal Calomel Electrode (NCE) is a device used to measure the electrical potential of a solution. It consists of a silver chloride electrode and a mercury-mercurous chloride electrode. While the NCE is the standard electrode in electrochemistry, there are several other types of electrodes that can be used for similar purposes. These include the saturated calomel electrode (SCE), which is similar to the NCE but has a higher concentration of mercurous chloride, and the silver-silver chloride electrode, which utilizes only a silver wire and silver chloride for its measurement. Other synonyms for the NCE include the Quinhydrone electrode, the Hydrogen electrode, and the Ag/AgCl electrode. Each of these electrodes has its own strengths and weaknesses, making it important for researchers to choose the right electrode for their specific applications.
