SUMMARY

The discussion centers on the formation of a white precipitate when chloride ions (Cl^-) are mixed with nitric acid (HNO₃) and silver nitrate (AgNO₃). The resulting precipitate is confirmed to be silver chloride (AgCl). The chemical reaction involved is represented as: X⁺ + Cl^- + H₃O⁺ + Ag⁺ + 2NO₃^- → XNO₃ + AgCl↓ + HNO₃ + H₂O. This reaction illustrates the interaction of univalent metal chlorides with silver nitrate in an acidic medium.

Silver Chloride ? AgCl
Consider the chloride of a unvalent metal:
X^{+}+Cl^{-}+H_{3}O^{+}+Ag^{+}+2NO_{3}^{-}\rightarrow XNO_{3}+AgCl\downarrow+HNO_{3}+H_{2}O
