Fine crystalline powder of white color, odorless. It dissolves very poorly in water, does not dissolve at all in alcohol, easily dissolves in dilute nitric and hydrochloric acids. Fireproof and even prevents combustion. Decomposes to water and calcium oxide when heated.
Strong alkali. It enters into a neutralization reaction with acids with the formation of salts - carbonates. When interacting with metals, explosive and flammable hydrogen is released. Reacts with carbon oxides (IV) and (II), with salts.
The reaction of obtaining calcium hydroxide by the “quenching” method occurs with a large release of heat, the water begins to boil, the caustic solution is sprayed in different directions - this must be taken into account when working.
