Acids and bases: Introduction - Chem1

2018/9/29· For example, a similar reaction can occur between acetic acid and calcium hydroxide to produce calcium acetate: 2 CH 3 COOH + Ca(OH) 2 → CH 3 COOCa + 2 H 2 O If this takes place in aqueous solution, the reaction is really between the very small quantities of H + and OH – resulting from the dissociation of the acid and the dissolution of the base, so the reaction is identical with (1) :

An Introduction To Water Hardness | ITACA

Lime (calcium hydroxide – Ca(OH) 2) and soda ash (sodium carbonate – Na 2 CO 3) is added to the water causing CaCO 3 and Mg(HO) 2 to precipitate out. In large municipal systems Ca(OH) 2 is added and the solid precipitates are removed though sedimentation however fine particles will remain, therefore carbon dioxide is bubbled through the water to turn these back into soluble bicarbonates.
