Question

Name the following polyatomic ions :

a. ${\mathrm{SO}}_4^{2-}$         b. ${\mathrm{CO}}_3^{2-}$

c. ${\mathrm{HSO}}_3^{-}$        d. ${\mathrm{NO}}_3^{-}$

Step-by-Step Solution

Answer

a. The name of the polyatomic ion ${\mathrm{SO}}_4^{2-}$ is sulfate.

b. The name of the polyatomic ion ${\mathrm{CO}}_3^{2-}$ is carbonate.

c. The name of the polyatomic ion ${\mathrm{HSO}}_3^{-}$ is hydrogen sulfite (bisulfite).

d, The name of the polyatomic ion ${\mathrm{NO}}_3^{-}$ is nitrate.

Part (a) Step 1 : Given information

We have to write the name of  ${\mathrm{SO}}_4^{2-}$  polyatomic ion.

Part (a) Step 2 : Simplification

• The chemical name of the polyatomic ion is Sulfate.
• Sulphate is composed of $\mathrm{S}$ (sulfur) and $\mathrm{O}$ (oxygen)

Part (b) Step 1 : Given information

We have to write the name of  ${\mathrm{CO}}_3^{2-}$ polyatomic ion.

Part (b) Step 2 : Simplification

• The chemical name of the polyatomic ion is Carbonate.
• Carbonate is composed of $\mathrm{C}$(carbon) and $\mathrm{O}$ (oxygen)

Part (c) Step 1 : Given information

We have to write the name of ${\mathrm{HSO}}_3^{-}$  polyatomic ion.

Part (c) Step 2 : Simplification

• The chemical name of the polyatomic ion is Hydrogen sulfite (bisulfite).
• Hydrogen sulfite is composed of $\mathrm{H}$(hydrogen) and ${\mathrm{SO}}_3^{2-}$ sulphite.

Part (d) Step 1 : Given information

We have to write the name of  ${\mathrm{NO}}_3^{-}$ polyatomic ion.

Part (d) Step 2 : Simplification

• The chemical name of the polyatomic ion is Nitrate.
• Nitrate is composed of $\mathrm{N}$ (nitrogen) and $\mathrm{O}$ (oxygen)
