Calcium+Hydroxide


 * Calcium hydroxide **, traditionally called ** slaked lime ** , is an inorganic compound with the chemical for mula Ca (OH )2. It is a colorless crystal or white powder and is obtained when calcium oxide (called // lime // or // quicklime // ) is mixed, or " slaked " with water . It has many names including ** hydrated lime ** , ** builders lime ** , ** slack lime ** , ** cal ** , or ** pickling lime ** . It is of low toxicity. Calcium hydroxide can react with carbon dioxide producing calcium carbonate and water. In industry calcium hydroxide is produced by heating calcium carbonate. Calcium hydroxide is used in many applications, including food preparation.

Can be used in water and sewage treatment and the paper industry.

Calcium hydroxide forms a fluffy charged solid that aids in the removal of smaller particles from water, resulting in a clearer product. This application is enabled by the low cost and non-toxicity of calcium hydroxide. It is also used in fresh water treatment for raising the pH of the water so that the pipes will not corrode whre the base water is acidic, because it is self-regulating and does not raise the pH too much. Unprotected exposesure can cause health risks and exposure should be limited. Exposure can cause severe skin irritation and chemical burns, blindness and lung damage.
