Question

The chemical formula of cupric nitrate 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 cupric nitrate as:

• The chemical symbol of the cupric ion is ${\mathrm{Cu}}^{+2}$
• The chemical symbol of nitrate ion is ${\left({\mathrm{NO}}_3\right)}^{-1}$
• Both ions combine together in a way such that

$$\begin{gathered} {\mathrm{Cu}}^{+2}{\left({\mathrm{NO}}_3\right)}^{-1} \\ 21(\mathrm{valency}\mathrm{is}\mathrm{cross}\mathrm{multiplied}\mathrm{to}\mathrm{get}\mathrm{the}\mathrm{compound}) \\ {\mathrm{Cu}}_1{\left({\mathrm{NO}}_3\right)}_2(\mathrm{simplifying}\mathrm{the}\mathrm{ratio}\mathrm{of}\mathrm{ions}) \\ \mathrm{Cu}{\left({\mathrm{NO}}_3\right)}_2 \end{gathered}$$

Conclusion: The chemical formula for cupric nitrate is $\mathrm{Cu}{\left({\mathrm{NO}}_3\right)}_2$
