    Calcium hydroxide (Ca (OH) 2, slaked lime or "fluff") is a chemical substance, a strong base. It is a white powder, poorly soluble in water.

    • When whitewashing premises.
    • When whitewashing wooden fences and coating rafters - to protect against rotting and fire.
    • For the preparation of lime mortar. Lime has been used for building masonry since ancient times. The mixture is usually prepared in the following proportion: three to four parts of sand (by weight) are added to one part of a mixture of calcium hydroxide (slaked lime) with water. In this case, the mixture solidifies according to the reaction: Ca (OH) 2 + CO2 → CaCO3 ↓ + H2O. This is an exothermic reaction, the energy release is 27 kcal (113 kJ). As you can see from the reaction, water is released during it. This is a negative factor, since the premises built with lime mortar have high humidity for a long time. In this regard, and also due to a number of other advantages over calcium hydroxide, cement has practically replaced it as a binder for building mortars.
    • For the preparation of silicate concrete. The composition of silicate concrete is the same as the composition of lime mortar, but it is prepared by a different method - a mixture of calcium oxide and quartz sand is treated not with water, but overheated (174.5-197, 4 ° C) with steam in an autoclave at a pressure of 9-15 atmospheres.
    • To remove the carbonate hardness of the water (water softening). The reaction proceeds according to the equation: Ca (HCO3) 2 + Ca (OH) 2 → 2CaCO3 ↓ + 2H2O.
    • For the production of bleach.
    • ;
    • For the production of lime fertilizers.
    • Causticizing sodium and potassium carbonate.
    • Leather tanning.
    • Obtaining other calcium compounds, neutralizing acidic solutions (including industrial waste water), obtaining organic acids, etc.
    • Registered as a food additive E526 in the food industry.
    • Lime water is a transparent solution of calcium hydroxide. It is used to detect carbon dioxide. When interacting with it, it becomes cloudy, as insoluble calcium carbonate is formed: Ca (OH) 2 + CO2 → CaCO3 ↓ + H2O.
    • Lime milk - suspension ( suspension) of calcium hydroxide in water, white and opaque. It is used for the production of sugar and the preparation of mixtures for combating plant diseases, whitewashing the trunks.
    • In dentistry, for disinfection of the root canals of teeth.
