A student cоmbines 40.0 mL оf 0.250 M leаd(II) nitrаte, Pb(NO3)2, with 60.0 mL оf 0.300 M potаssium iodide, KI. A bright-yellow precipitate of lead(II) iodide forms: Pb(NO3)2(aq) + 2KI(aq) → PbI2(s) + 2KNO3(aq) Write the balanced net ionic equation, and classify the reaction as acid–base, oxidation–reduction, or precipitation. Determine the limiting reactant. Show your work. Calculate the mass of PbI2 precipitate that forms. Calculate the concentration of nitrate ion, NO3-, in the final solution. Assume the volumes are additive. The KNO3 formed in this reaction remains fully dissolved in the water. In terms of interparticle interactions, explain why an ionic compound such as KNO3 dissolves readily in water.
