Introduction

Mercury is a chemical element with the symbol Hg and atomic number 80. A heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.
Mercury ions, which pose a high danger to human health and the environment, are exposed to inhalation of inorganic mercury vapor released during the process of gold mining and when fed with seafood that accumulates organic mercury.

Principle

An ideal ion-selective electrode (I.S.E.) consists of a thin membrane across which only the intended ion can be transported. The transport of ions from a high conc. to a low one through a selective binding with some sites within the membrane creates a potential difference.

Applications

• Used for the potentiometric determination of several anions (fluoride, chloride, bromide, iodide ion) and cations (sodium, potassium, calcium ion).
• Used for endpoint detection in potentiometric titration.
• In biochemistry, ion selective electrodes are used for the determination of enzymes and substances which interact with enzymes.
