Solution

Solution Steps

Step 1: Identify the cation and anion for each compound

For each row in the table, identify the cation and anion provided.

For the first row:
- Cation: $\mathrm{Na}^{+}$
- Anion: $\mathrm{ClO}_{2}^{-}$
For the second row:
- Cation: $\mathrm{K}^{+}$
- Anion: $\mathrm{NO}_{2}^{-}$
For the third row:
- Cation: $\mathrm{Na}^{+}$
- Anion: $\mathrm{ClO}_{3}^{-}$

Step 2: Determine the name of each compound

Using the names of the cations and anions, determine the name of each compound.

For $\mathrm{NaClO}_{2}$:
- Cation: Sodium ($\mathrm{Na}^{+}$)
- Anion: Chlorite ($\mathrm{ClO}_{2}^{-}$)
- Compound name: Sodium chlorite
For $\mathrm{KNO}_{2}$:
- Cation: Potassium ($\mathrm{K}^{+}$)
- Anion: Nitrite ($\mathrm{NO}_{2}^{-}$)
- Compound name: Potassium nitrite
For $\mathrm{NaClO}_{3}$:
- Cation: Sodium ($\mathrm{Na}^{+}$)
- Anion: Chlorate ($\mathrm{ClO}_{3}^{-}$)
- Compound name: Sodium chlorate

Final Answer

\[ \begin{array}{|c|c|c|c|} \hline \multicolumn{4}{|c|}{\text{Some ionic compounds}} \\ \hline \text{cation} & \text{anion} & \text{empirical formula} & \text{name of compound} \\ \hline \mathrm{Na}^{+} & \mathrm{ClO}_{2}^{-} & \mathrm{NaClO}_{2} & \boxed{\text{Sodium chlorite}} \\ \hline \mathrm{K}^{+} & \mathrm{NO}_{2}^{-} & \mathrm{KNO}_{2} & \boxed{\text{Potassium nitrite}} \\ \hline \mathrm{Na}^{+} & \mathrm{ClO}_{3}^{-} & \mathrm{NaClO}_{3} & \boxed{\text{Sodium chlorate}} \\ \hline \end{array} \]
