Question

The chemical formula for ammonium sulphate is_____

Answer 1

Chemical formula

• A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element.

The chemical formula for ammonium sulphate as:

• The chemical symbol of ammonium ion is ${\left({\mathrm{NH}}_4\right)}^{+1}$
• The chemical symbol of sulphate ion is ${\left({\mathrm{SO}}_4\right)}^{-2}$
• Both ions combine together in a way such that

$$\begin{gathered} {\left({\mathrm{NH}}_4\right)}^{+1}{\left({\mathrm{SO}}_4\right)}^{-2} \\ 12(\mathrm{valency}\mathrm{is}\mathrm{cross}\mathrm{multiplied}\mathrm{to}\mathrm{get}\mathrm{the}\mathrm{compound}) \\ {\left({\mathrm{NH}}_4\right)}_2({\mathrm{SO}}_4{)}_1(\mathrm{simplifying}\mathrm{the}\mathrm{ratio}\mathrm{of}\mathrm{ions}) \\ {\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4 \end{gathered}$$

Conclusion: The chemical formula for ammonium sulphate is ${\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4$
