Answer 2

Answer: The correct answer is sodium chloride.

Explanation:

We are given:

Sodium nitrate, sodium carbonate, sodium sulfate and sodium chloride.

All the salts have same cation which is sodium ion.

Anions of the given salts are nitrate ions $(NO_3^-)$ , carbonate ions $(CO_3^{2-})$ , sulfate ions $(SO_4^{2-})$ and chloride ions $(Cl^-)$

Out of the anions, one ion is a monoatomic ion which is chloride ion, rest all are polyatomic ions.

Polyatomic ions are defined as the ions which are formed by the combination of two or more different atoms.

Hence, the correct answer is sodium chloride.
