Final answer:
When aqueous solutions of silver nitrate and potassium iodide are mixed, a precipitation reaction occurs. Silver iodide is formed as a yellow precipitate.
Step-by-step explanation:
A precipitation reaction occurs when aqueous solutions of silver nitrate and potassium iodide are mixed. In this reaction, silver iodide is formed as a yellow precipitate.
The balanced chemical equation for this reaction is:
AgNO3(aq) + KI(aq) → AgI(s) + KNO3(aq)
