Question

Write down the chemical formula of Barium sulphate.

Answer 1

Ions present in Barium sulphate:

1. Barium sulphate contains one barium ion $\mathbf{\left(}{\mathbf{Ba}}^{\mathbf{2}\mathbf{+}}\mathbf{\right)}$ i.e. barium cation and one sulphate ion $\mathbf{\left(}{\mathbf{SO}}_{\mathbf{4}}^{\mathbf{2}\mathbf{-}}\mathbf{\right)}$ i.e. sulphate anion.
2. Thus, Barium sulphate is an ionic compound.

The chemical formula of Barium sulphate is $\mathbf{\left(}{\mathbf{BaSO}}_{\mathbf{4}}\mathbf{\right)}$.
