The Sr(IO 3 ) 2 could get too warm and wash away in the water, the precipitate could not completely form when mixing the reactants, and some precipitate could become stuck in the beaker and not wash out. Those are factors that are not all easily controlled, so overall my percent yield of 96.05.% seems plausible when looking at those factors that could affect the results.

If I were to repeat this experiment, I would probably take more time in letting the reactants mix and form the precipitate. That way I could be sure almost all the precipitate actually formed. I would also keep the wash bottle in colder conditions to make sure none of the precipitate washed away. Answers to questions Pre-Lab Assignment 2(1) Supernatant liquid: the usually clear liquid overlying material deposited by settling, precipitation, or centrifugation. 2(2) Limiting reagent: the reactant in a chemical reaction that limits the amount of product that can be formed. 2(3) Theoretical yield: amount that can be produced as found from correct computations. 2(4) Decantation: the process of pouring the supernatant liquid into the funnel assembly without disturbing the precipitate at the bottom of the beaker.
