X is Calcium oxide.
The element is Calcium.

When water is added to calcium oxide, it forms calcium hydroxide.
CaO + H2O - Ca(OH)2
where calcium oxide is a base and hence turns red litmus blue.

The element is Calcium and the substance X is Calcium Oxide (CaO). Calcium oxide is used
extensively in the cement industry and Calcium is present in our bones in the form of Calcium Phosphate.
CaO+H2O→Ca(OH)2
Calcium oxide dissolves in water to form a basic solution which turns red litmus blue
