Question

The chemical formula for ferric phosphate 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 ferric phosphate as:

• The chemical symbol of ferric ion is ${\mathrm{Fe}}^{+3}$
• The chemical symbol of phosphate ion is ${\left({\mathrm{PO}}_4\right)}^{-3}$
• Both ions combine together in a way such that

$$\begin{gathered} {\mathrm{Fe}}^{+3}{\left({\mathrm{PO}}_4\right)}^{-3} \\ +3-3(\mathrm{valency}\mathrm{is}\mathrm{cross}\mathrm{multiplied}\mathrm{to}\mathrm{get}\mathrm{the}\mathrm{compound}) \\ {\mathrm{FePO}}_4(\mathrm{simplifying}\mathrm{the}\mathrm{ratio}\mathrm{of}\mathrm{ions}) \end{gathered}$$

Conclusion: The chemical formula for ferric phosphate is ${\mathrm{FePO}}_4$
