What is Potassium Chloride?

Potassium chloride (KCl) is a metal salt compound produced from binding chlorine and potassium together. It is found in crystal form and is not dissimilar to sodium chloride. In a flame test, potassium chloride results in a lilac flame result.

Potassium chloride readily dissolves in water and is an extremely stable compound that is often used in laboratories. ReAgent stocks this product in crystal form and can fulfil any specific pack size requirements you may have.

Whilst the human body does require potassium in order to function, this product is NOT FOR HUMAN CONSUMPTION. Ingestion of any foreign chemicals can be dangerous or fatal and care should be taken when handling any chemical substance.

What is Potassium Chloride Used For?

Potassium Chloride shares some uses with sodium chloride due to the physical nature of the substance. It has many industrial uses, such as:

  • Making fertiliser, as many plants rely on an intake of potassium
  • A de-icing agent that is safer to use around plants and animals
  • An alternative to sodium chloride in a household water softener
  • In medicine, as potassium is required by the human body
  • Mixing with table salt to improve taste
  • In cardiac surgical applications to stop the heart when an operation cannot be performed when the heart is beating
  • In the lethal injection, because of its lethal effects
