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
