Silver nitrate is a commonly used reagent for detecting the presence of chloride ions in salt. When silver nitrate is added to a solution containing chloride ions, a white precipitate of silver chloride is formed. This reaction is highly specific for chloride ions and is widely used in qualitative salt analysis.

Incorrect options:

2) Potassium dichromate: Potassium dichromate is not a reagent used for detecting chloride ions. It is commonly used as an oxidizing agent and in the determination of organic compounds.

3) Potassium permanganate: Potassium permanganate is not a reagent used for detecting chloride ions. It is a strong oxidizing agent used for the determination of reducing agents.

4) Sodium hydroxide: Sodium hydroxide is not a reagent used for detecting chloride ions. It is a strong base used in the identification of acidic and basic radicals in salt analysis.
