Lime water - Wikipedia, the free encyclopedia
Lime water is the common name for saturated calcium hydroxide solution. Its chemical formula is Ca(OH) 2 . Since calcium hydroxide is only sparsely soluble, i.e. ca. 1.5g per liter at 25°C, there i...

This reaction is reversible; calcium oxide will react with carbon dioxide to form calcium carbonate. The reaction is driven to the right by ... At room temperature, the reaction of lime with carbon dioxide is very slow. It is speeded by mixing lime with water. When lime is mixed with water, it forms calcium hydroxide,
