During a gravimetric analysis experiment to determine the salt (nacl) content of a chicken soup sample, a precipitate of silver chloride was produced, dried and weighed. the sources of error in the analysis includei) the precipitate was not washed before it was dried. ii) the soup contained some sodium iodide in addition to the sodium chloride. iii) some precipitate remained in the reaction flask after the filtration process. which of these errors could account for a lower than expected mass of silver chloride precipitate?

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
