Answer:

PbI₃ is the precipitate in the reaction

Explanation:

A precipitate is defined as a substance than appears after a chemical reaction because of the formation of an insoluble compound.

You can identify yhe precipitate in a chemical reaction because its state is solid (s). For example, in the reaction:

Pb(NO₃)₃(aq) + 3KI(aq) → PbI₃(s) + 3KNO₃(aq)

The Pb(NO₃)₃ and KI are soluble salts (Because are in (aq) medium) but the reaction produce a solid, PbI₃ and a soluble salt, KNO₃. The solid,

PbI₃ is the precipitate in the reaction
