Question

A substance X, which is an oxide of an element, is used intensively in the cement industry.
This element is present in bones also. On treatment with water it forms a solution which
tums red litmus blue.
El (A) Identify X
(b) Identify the type of reaction.
(C) Write a balanced chemical equation for the above reaction.
Write the common name of the product formed.
What happens when carbon dioxide gas is passed through clear solution of above compound​

Answer 1

Answer:

Explanation:

A Group II element is used extensively in the cement industry, the element also present in our bones. With the treatment with water it forms a solution which turns red litmus into blue litmus. Thus, the element is calcium.  

CaO (Calcium oxide) is extensively used in ‘cement industry. The amount of calcium in the bones determine the strength of the bone calcium and water together forms calcium hydroxide which is alkaline and converts red litmus paper blue.

The balanced chemical equation formed will be -

CaO +H2O ------- Ca(OH)2

Calcium hydroxide which is an base..thus turns red litmus to blue.
