Question

Write the correct formula for the following ionic compounds :

a. aluminum chlorate                            b. ammonium oxide

c. magnesium bicarbonate                   d. sodium nitrite

e. copper(I) sulfate

Step-by-Step Solution

Answer

a. The correct formula of the ionic compound aluminum chlorate is $\mathrm{Al}{\left({\mathrm{ClO}}_3\right)}_3$

b. The correct formula of the ionic compound ammonium oxide ${\left({\mathrm{NH}}_4\right)}_2\mathrm{O}$

c. The correct formula of the ionic compound magnesium bicarbonate ${\mathrm{MgCO}}_3$

d. The correct formula of the ionic compound sodium nitrite ${\mathrm{NaNO}}_2$

e. The correct formula of the ionic compound copper(I) sulfate ${\mathrm{CuSO}}_4$

Part (a) Step 1 : Given information

We have to write the name of aluminum chlorate ionic compound.

Part (a) Step 2 : Simplification

• We know that ${\mathrm{Al}}^{3+}$ is aluminum and ${\mathrm{ClO}}_3^{-}$ is chlorate.
• So, the correct formula of the ionic compound aluminum chlorate is $\mathrm{Al}{\left({\mathrm{ClO}}_3\right)}_3$

Part (b) Step 1 : Given information

We have to write the name of ammonium oxide ionic compound.

Part (b) Step 2 : Simplification

• We know that ${\mathrm{NH}}_4^{+}$ is ammonium and ${\mathrm{O}}^{2-}$ is oxygen.
• So. the correct formula of the ionic compound ammonium oxide is ${\left({\mathrm{NH}}_4\right)}_2\mathrm{O}$
  

Part (c) Step 1 : Given information

We have to write the name of magnesium bicarbonate ionic compound.

Part (c) Step 2 : Simplification

• We know that ${\mathrm{Mg}}^{2+}$ is magnesium and ${\mathrm{CO}}_3^{2-}$ is carbonate.
• So, the correct formula of the ionic compound magnesium bicarbonate is ${\mathrm{MgCO}}_3$
  

Part (d) Step 1 : Given information

We have to write the name of sodium nitrite ionic compound.

Part (d) Step 2 : Simplification

• We know that ${\mathrm{Na}}^{+}$ is Sodium and ${\mathrm{NO}}_3^{-}$ is nitrite.
• So, the correct formula of the ionic compound sodium nitrite is ${\mathrm{NaNO}}_3$
  

Part (e) Step 1 : Given information

We have to write the name of copper(I) sulfate ionic compound.

Part (e) Step 2 : Simplification

• We know that ${\mathrm{Cu}}^{2+}$ is copper and ${\mathrm{SO}}_4^{2-}$ is sulphate.
• So, the correct formula of the ionic compound copper(I) sulfate is ${\mathrm{CuSO}}_4$
