Chloride ion.
✓
Answer
A small amount of the salt is taken in a test tube and conc. $H_2SO_4$ is added to it and then test tube is warmed, if a colourless gas with pungent odour is evolved then chloride ions are present in the salt. It can be confirmed by bringing a glass rod dipped in ammonia solution near the gas evolved, if dense white fumes are formed then presence of chloride ions is confirmed.
