I can help you with your question.

According to Google Translate, your question is:

Answer in detail. Help, please! After adding which substance in the solution can chloride ions be detected? Choose one answer: a. NaCl b. AgNO3 c. KClO4 d. AlCl3 e. NH4Cl f. MgCl2 g. HCl h. KClO3

The correct answer is b. AgNO3. This is because silver nitrate (AgNO3) reacts with chloride ions (Cl-) to form a white precipitate of silver chloride (AgCl), which is insoluble in water. This is a way to test for the presence of chloride ions in a solution. The reaction is:

AgNO3(aq) + Cl-(aq) -> AgCl(s) + NO3-(aq)

None of the other substances will form a precipitate with chloride ions, so they cannot be used to detect them. You can find more information about this topic on this website. I hope this helps you.
