Description

When whitewashing rooms.
For preparation of limy construction solution. Lime was applied to a construction laying since ancient times. Mix is usually prepared in such proportion: add three to one part of mix of hydroxide of calcium (extinguished lime) with water — four parts of sand (on weight). At the same time there is a hardening of mix on reaction: Ca (OH) 2 + CO2 → CaCO3 ↓ + H2O. It is exothermic reaction, allocation of energy makes 27 kcal (113 kJ). At the same time there is also a formation of silicate of calcium: CaCO3 + SiO2 → CaSiO3 + CO2 ↑. Apparently from reaction, during it water is emitted. It is a negative factor as in the rooms built by means of limy construction solution, long time remains the increased humidity. In this regard, and also thanks to some other advantages before calcium hydroxide, cement practically forced out it as binding construction solutions.
For preparation of silicate concrete. The composition of silicate concrete is identical with composition of limy construction solution, however it prepares by other method — mix of oxide of calcium and quartz sand is processed not by water, and overheated (174,5 — 197,4 °C) water vapor in the autoclave with a pressure of 9 — 15 atmospheres.
For elimination of carbonate hardness of water (water softening). Reaction goes on the equation: Ca (HCO3) 2 + Ca (OH) 2 → 2CaCO3 ↓ + 2H2O.
For production of chloric lime.
For production of limy fertilizers.
Kaustifikation of a carbonate of sodium and potassium.
Tanning of skin.
Receiving other compounds of calcium, neutralization of sour solutions (including sewage of productions), receiving organic acids and so forth.
In the food industry it is registered as a food additive of E526.
Lime water — transparent solution of hydroxide of calcium. It is used for detection of carbon dioxide. At interaction with it it grows turbid as the insoluble carbonate of calcium is formed: Ca (OH) 2 + CO2 → CaCO3 ↓ + H2O.
— weigh limy milk (suspension) of hydroxide of calcium in water, white and opaque. It is used for production of sugar and preparation of mixes for fight against diseases of plants, whitewashing of trunks.
In stomatology — for disinfection of root channels of teeth.
