The equation AgNO3 + KI -> AgI + KNO3

  1. The chemical equation AgNO3 + KI -> AgI + KNO3representsthechemicalreactionprocessbetweenSilverNitrate(AgNO3)andPotassiumIodide(KI), resulting in Silver Iodide (AgI) and Potassium Nitrate (KNO3).

  2. 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.

  3. 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.

  4. 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.
