Question

What is the chemical name of \[{H_2}S{O_4}\].

Answer 1

Hint: The chemical name of any compound in chemistry is derived from its molecular formula. Since, \[{H_2}S{O_4}\] is an ionic compound the systematic naming will be done in such a manner that the cations are named first and the anions are named after the naming of cations.

Complete answer:
The process of giving a chemical name to a compound is initiated by determining the elements involved in its formation and the nature of their existence. Some elements exist individually and some of them exist as a molecule and are therefore named accordingly.
The formula of the given compound \[{H_2}S{O_4}\] tells us that it contains two hydrogen atoms, one sulphur atom and four oxygen atoms in a single molecule. But the systematic naming of this compound will not involve individual names of all these elements.
The given compound is ionic and a binary compound therefore only the ions will be named. Hydrogen ions will be named as they are the cations and named first. The group of sulphur and oxygen atoms would be treated as a whole and the anion is called the sulphate anion.
\[ \therefore \] The chemical name of the compound \[{H_2}S{O_4}\] is Dihydrogen sulphate.

Note:
The common name of the compound \[{H_2}S{O_4}\] is Sulphuric acid which is also sometimes used as it’s chemical name but this name is not derived from its formula and therefore does not contain information about the ions involved in the formation of the compound.
