The chemical equation AgNO3 + KI -> AgI + KNO3representsthechemicalreactionprocessbetweenSilverNitrate(AgNO3)andPotassiumIodide(KI), resulting in Silver Iodide (AgI) and Potassium Nitrate (KNO3).
-
Reaction conditions:
- Temperature: This reaction occurs at room temperature.
- Light: It is best to carry out under conditions without strong light because AgI can decompose under the influence of light.
- Environment: The reaction occurs in an aqueous solution environment.
-
Reaction process:
- This reaction is a substitution reaction, where the I- radical replaces the NO3- radical at the Ag+ ion, forming AgI and KNO3.
- This reaction is also known as an ion exchange reaction.
-
Phenomena observed:
- When AgNO3 and KI meet in solution, a light yellow precipitate of AgI appears.
- This precipitate does not dissolve in the solution, resulting in a cloudy phenomenon in the solution.
