What precipitate forms when silver nitrate reacts with potassium iodide?

Silver nitrate and potassium iodide form silver iodide, an insoluble yellow precipitate. Potassium and nitrate ions remain dissolved in the solution.

Burner off · Analysis waits for you
A beaker is prepared with Silver nitrate and Potassium iodide. The burner stays off, and you decide when to analyze.

Supported prediction

AgNO3(aq) + KI(aq) -> AgI(s) + KNO3(aq)

What the equation means

Silver nitrate and potassium iodide undergo a precipitation reaction. Insoluble silver iodide forms as a yellow solid while potassium and nitrate ions remain in solution. The molecular equation has a one-to-one reactant ratio.

Expected observation

A yellow silver iodide precipitate

OmniLab shows a bounded yellow precipitate cue inside the beaker to represent the expected silver iodide solid.

Three safety notes

Read these before any physical experiment

  1. 01

    Wear gloves and splash goggles when handling silver nitrate.

  2. 02

    Protect the silver iodide precipitate from strong light.

  3. 03

    Collect silver-containing waste for approved disposal.

These guides use the same pattern: predict the equation, identify the visible cue, then check what the virtual model leaves out.
