What is Calcium Hydroxide? Calcium Hydroxide (chemical formula Ca(OH)₂), is an inorganic compound commonly known as slaked lime. It is a strong base that is primarily used in the production of other chemicals, as well as in water treatmentand construction. Alternate names for Calcium Hydroxide include Hydrated Lime and Slaked Lime.

Frequent Uses

Chemical Synthesis
Acts as a base in organic and inorganic chemical reactions, such as the preparation of calcium salts or other chemicals in lab settings.

pH Adjustment
Utilised in laboratory experiments that require a specific pH level, particularly in reactions where maintaining a mildly alkaline environment is essential.

Precipitation Reactions
Employed in the laboratory for the precipitation of certain compounds, such as in the separation of heavy metals from solutions.

Testing for Carbon Dioxide
Calcium hydroxide solution, known as limewater, is used in laboratory tests to detect the presence of carbon dioxide, as it turns milky when CO₂ is bubbled through it.

  • A flocculant, in water and sewage treatment and improvement of acid soils
  • An ingredient in whitewash, mortar, and plaster
  • An alkali used as a lye substitute in no-lye hair relaxers
  • For reef aquarium hobby for adding bio-available calcium in solution for calcium-using animals such as algae, snails, hard tube worms, and corals (often referred to as Kalkwasser mix), and also to increase the alkalinity of the water
