Sulphuric acid, also called ‘king of chemicals' has the formula H2SO4. Its appearance is different from that of hydrogen and sulphur. Give two other reasons why sulphuric acid is a compound and not a mixture.

Explanation:

Before proceeding to answering the question, we have t understand what we mean by both mixture and compound.

A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids.

A compound on the other hand is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds.

The two other reason why H2SO4 is a compound and not a mixture are;

1)  The components which are Hydrogen, Sulphur and Oxygen cannot be separated by physical means.

2) It has a constant melting and boiling point.
