me: White precipitate of BaSO₄. Potassium Iodide and Lead Nitrate: \[ 2 \ \mathrm{KI (aq)} + \mathrm{Pb(NO_3)_2 (aq)} \rightarrow \mathrm{PbI_2 (s)} + 2 \ \mathrm{KNO_3 (aq)} \] Expected outcome: Bright yellow precipitate of PbI₂. Factors Affecting Precipitation Precipitation depends on several vari
