Prove through experiments that the dry salt given to you is sodium chloride.

In order to prove that the obtained dry salt is sodium chloride, we need to understand the structure of the above substance. Chemical formula of sodium chloride NaCl. Table salt can be represented as a sodium cation, which has a positive charge of Na + and an anion of chlorine, which has a negative charge of Cl -.

Sodium cation can be detected on combustion and produces a characteristic yellow flame when burnt. The chlorine anion can be determined by a qualitative reaction with silver nitrate AgNO3. When sodium chloride and silver nitrate react, a sodium nitrate salt and a silver chloride salt are formed, which precipitates and has the characteristic appearance of a white powder. The molecular equation of the reaction can be written as follows:

NaCl + AgNO3 = AgCl ↓ + NaNO3.
