Percent Yield Lab Questions 1) You would not be able to achieve 100% of the product because there are always ways that some of the product residue can be left over on the sides of the funnel or the sides of the beaker. 2) If you receive more than 100% yield, it means something went wrong. The precipitate could have not dried completely when the mass was taken or the filter paper mass could have been affected by the tear put in it when making the funnel. 3) It is important to know the true percent yield of any reaction because then you will be able to compare the percent yield acquired in your lab procedure to the actual percent yield, in a way checking your answer, and making sure you can find out the errors you made in your lab in case your…show more content…
In order to collect the data, a certain procedure was followed. This started with recording the mass of a beaker with contaminated sand in it. Then, a funnel made of filter paper was placed in a flask and the sand was poured into the funnel. Distilled water was used to rinse the sand. A different beaker was then cleaned and dried out and the mass of the beaker was taken and recorded. Potassium iodide was added into the beaker containing the rinse water. Then, another filter paper was weighed and the data was recorded. Another funnel was made out of the filter paper and put in a beaker. The potassium iodide mixture was poured into the funnel. The wet funnel was then dried and the mass of the dried funnel was recorded. The percent yield of lead (II) iodide from research calculations is 85.0%. The percent yield of lead (II) iodide, which was acquired through the procedure of the lab, was 100%. The percent of lead in lead (II) nitrate is 62.6%. The theoretical yield of lead (II) iodide is 0.01
