Vedclass · Answer

(A) The substance $X$ is Calcium oxide $(CaO)$, commonly known as quicklime.$1$. It is an oxide of Calcium, which is a group $2$ element.$2$. Calcium is a major component of bones in the form of calcium phosphate.$3$. It is used extensively in the cement industry.$4$. When $CaO$ reacts with water, it forms Calcium hydroxide $(Ca(OH)_2)$, which is a strong base and turns red litmus blue.The chemical reaction is:$CaO(s) + H_2O(l) \longrightarrow Ca(OH)_2(aq) + 	ext{Heat}$

$A$ substance $X$, which is an oxide of a group $2$ element, is used intensively in the cement industry. This element is present in bones also. On treatment with water, it forms a solution which turns red litmus blue. Identify $X$ and write the chemical reactions involved.
