Question

Write the chemical formula for Zinc Hydroxide.

Answer 1

• The Zinc ion is denoted by ${\mathrm{Zn}}^{2+}$.
• The hydroxide ion is denoted by ${\mathrm{OH}}^{-}$.
• Interchanging the valencies, we get
• ${\mathrm{Zn}}^{2+}⥂{\mathrm{OH}}^{-}$ becomes $\mathrm{Zn}{\left(\mathrm{OH}\right)}_2$

Therefore, the chemical formula for Zinc Hydroxide is $\mathrm{Zn}{\left(\mathrm{OH}\right)}_2$.
