The chemical formula of lime or quicklime is CaO. The chemical name of lime is calcium oxide. On the other hand, the chemical formula of limewater is Ca(OH) 2 and the chemical name of this substance is calcium hydroxide.
Chemical Formula. Ca (OH)₂ (Calcium hydroxide) Lime Water Test. Lime water turns milky/cloudy when carbon dioxide is passed through it, indicating the presence of carbon dioxide. Example: CO₂ + Ca (OH)₂ → CaCO₃ + H₂O (Milky/cloudy appearance) Oxidation/Reduction.
Lime water or milk of lime is the common name for saturated calcium hydroxide solution. Its chemical formula is Ca(OH) 2. The term is based on the mineral sense of lime, rather than the fruit sense of lime. Lime water used as a paint is called lime wash (see whitewash).

Lime Dosage Calculation for Carbonate Hardness Removal. The lime-soda ash water softening process uses lime (Ca(OH) 2), and soda ash (Na 2 CO 3), to precipitate hardness from solution. Carbonate hardness (calcium and magnesium bicarbonates) is complexed by lime.
lime. Reading time: 25 minutes. Lime is the most widely used reagent in water treatment applications. It is supplied in two forms: quick lime: CaO; slaked (or hydrated) lime: Ca (OH) 2. Warning: in both cases, these reagents will contain between 4 and 20% of solid impurities (CaCO 3, SiO 2 …).
Quick Reference. A saturated solution of calcium hydroxide in water. When carbon dioxide gas is bubbled through limewater, a ‘milky’ precipitate of calcium carbonate is formed:Ca (OH) 2 (aq)+CO 2 (g) → CaCO 3 (s)+H 2 O (l) If the carbon dioxide continues to be bubbled through, the calcium carbonate eventually redissolves to form a clear ...
