Calcium hydroxide has many names including hydrated lime, caustic lime, builders' lime, slaked lime, cal, and pickling lime. Calcium hydroxide is used in many applications, including food preparation, where it has been identified as E number E526. Limewater, also called milk of lime, is the common name for a saturated solution of calcium hydroxide.

Calcium deposits, primarily composed of calcium carbonate (CaCO 3), react with weak acids to form calcium salts that are soluble in water. The general reaction can be represented as follows: CaCO 3 + 2H + → Ca 2+ + CO 2 + H 2 O. Here, H + represents the hydrogen ions provided by the acid.
Lime water can make that a whole lot easier. A fresh-squeezed lime is “going to add about 11 calories to the water that you’re drinking, about 51 milligrams of potassium, less than 1 gram of ...
However, this does not apply for a normal use on common trees with green leaves. Diluted solutions of lime sulfur (between 1:16 and 1:32) are also used as a dip for pets to help control ringworm (a fungus), mange and other dermatoses and parasites. Undiluted lime sulfur is corrosive to skin and eyes and can cause serious injury like blindness.
Ca 2+ + 2 HCO − 3 ⇌ Ca 2+ + CO 2− 3 + CO 2 + H 2 O. Note that CO 2 is dissolved in the water. Carbon dioxide dissolved in water (aq) tends to equilibrate with carbon dioxide in the gaseous state (g): CO 2 (aq) ⇌ CO 2 (g) The equilibrium of CO 2 moves to the right, toward gaseous CO 2, when water temperature rises or
