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.
Free Chemistry calculator - Calculate chemical reactions and chemical properties step-by-step.
To calculate quicklime or hydrated lime dosage, mg/L, use the following equation: Where: A = CO 2 in source water (mg/L as CO 2 x 56/44) B = bicarbonate alkalinity removed in softening (mg/L as CaCO 3 x 56/100) C = hydroxide alkalinity in softener effluent (mg/L as CaCO 3 x 56/100) D = magnesium removed in softening (mg/L as Mg x 56/24.3)
limewater. in A Dictionary of Chemistry (6) Length: 73 words. 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)+CO2 (g) → CaCO3 (s)+H2O (l) If the carbon dioxide continues to be bubbled through, the calcium ...
This page looks at the origin and uses of limestone, and its conversion into quicklime, CaO, and slaked lime, Ca (OH) 2. Chemically, limestone is calcium carbonate. It is a sedimentary rock formed from the shells and skeletons of marine creatures which fell to the bottom of ancient seas.
