Answer 1

NaCl + AgNO3 = AgCl(осадок) + NaNO3

AgCl - белый творожистый осадок

Ag+ + Cl- = AgCl(осадок)

Answer 2

Qualitative Reaction for Determining Chloride Ions

To determine the presence of chloride ions, you can perform a qualitative reaction using silver nitrate (AgNO3) solution. When silver nitrate is added to a solution containing chloride ions, a white precipitate of silver chloride (AgCl) is formed. The reaction can be represented in ionic form as follows:

Ag+ + Cl- → AgCl

The white precipitate of silver chloride is insoluble in water and can be easily observed. The formation of this precipitate confirms the presence of chloride ions in the solution.

Please note that the color of the precipitate is white, not the color of the solution itself. The solution may be colorless or have a different color depending on the other substances present in it.

I hope this helps! Let me know if you have any further questions.
