Log in. Calcium also gives water a better taste. Answered Calcium oxide + water gives rise to calcium hydroxide 1 See answer Ask your question. Calcium oxide is frequently used to "lime" lake waters that have been acidified by acid rain it reacts with them and neutralizes acids in the lake. This process is called slaking. About 11% of these are Oxide, 0% are Other Chemicals. Ca (OH) 2 (s) + CO2 → CaCO3 (s) + H2O (g) Calculate the standard It may cause the lime water to splash out of the container and damage eyes or skin. These are termed as oxides because here, oxygen is in combination with only one element. shivam6226tomar shivam6226tomar 07.09.2019 Chemistry Secondary School +5 pts. Reaction of the oxides with dilute acids. Calcium oxide is calcinated or recalcinated lime having a moisture adsorptive capacity of not less than 28.5% by weight. The following reaction takes place: CaO + H 2 O -----> Ca(OH) 2 ΔH<<0 This reaction is highly exothermic.If water is dripped slowly onto a lump of calcium oxide, a hissing is heard as excess water is turned to steam by the heat produced in the reaction. Alibaba.com offers 543 calcium oxide with water products.
