Final answer:
When solutions of sodium iodate and silver nitrate are combined, a double displacement reaction occurs to form silver iodate as a precipitate.
Step-by-step explanation:
When solutions of sodium iodate and silver nitrate are combined, a double displacement reaction occurs. The balanced chemical equation for the reaction is:
2 NaIO3 + AgNO3 → 2 AgIO3 + NaNO3
In this reaction, the sodium ions from sodium iodate switch places with the silver ions from silver nitrate, forming silver iodate as a precipitate. The sodium nitrate remains dissolved in the solution.
