product of this experiment

lead (ii) iodide - PbI₂ insoluable

theoretical yield of lead (ii) iodide

the calculated amount of precipitate formed according to the stoichiometry of the reaction the maximum amount of product you can get calculated from the limiting reagent

supernate

the liquid lying above a solid residue after crystallization, precipitation, centrifugation, or other process

actual yield of lead (ii) iodide

the mass of the precipitate actually obtained in the experiment never more than the theoretical yield

limiting reagent

the substance that is totally consumed by the end of the experiment

stoichiometry

using known quantities from a chemical reaction and calculating unknown quantities

balanced equation of this experiment

Pb(No3)2 + 2 KI = 2 KNo3 + PbI2

percent yield

found by comparing the actual yield to the theoretical yield and expressing the ratio as a percentage the actual yield divided by the theoretical yield x 100 ratio of actual yield to theoretical yield

where will the product be collected?

in a cone of filter paper

potassium iodide + lead (II) nitrate ->

lead(II) iodide

solutions that will be mixed (reactants)

potassium iodide - KI lead (ii) nitrate - Pb(NO₃)₂
