Question

A substance X which is an oxide of a metal 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 also write the equation for its chemical reaction with water.

Answer 1

X...is calcium oxide (Cao)

It reacts with water to form aquas solution of ...slaked lime (Ca(oH)2)

Cao + H2O. -------------> Ca(OH)2

Answer 2

[Hello]

A Substance $<b><u>"CALCIUM OXIDE"$ which is an Oxide of a metal is used in intensively in the cement industry and house.



The elements"Calcium Oxide" present in human body which in part of Bone.

When we treat it's with water turned into red to litmus because it's basic in nature .

When Calcium Oxide reacts with water then:-

Cao+H20-----> Ca(OH)2

Hope it's helpful for you:-
