– The product was insufficiently dried before weighing. – Some of the product was lost during the transfer from the Buchner funnel to the evaporating dish. – 7.5 mL of FeCl3 was added instead of 3.0 mL as outlined in the procedure. – 4.587g of K2C2O4H2O was used instead of exactly 4.000g . – The recrystallization step was skipped and the
If all other variables were kept constant, determine the
effect that the following errors would have on the calculated
percent yield of the product. Would the yield be expected to
increase, decrease, or would there be no effect? Explain
your reasoning.
– The product was insufficiently dried before weighing.
– Some of the product was lost during the transfer from
the Buchner funnel to the evaporating dish.
– 7.5 mL of FeCl3 was added instead of 3.0 mL as
outlined in the procedure.
– 4.587g of K2C2O4H2O was used instead of exactly
4.000g .
– The recrystallization step was skipped and the
experiment went straight to vacuum filtration.
Given :some different reasoning.
To find : effect on the percent yield.
Concept : As we know that, the percent yield of any substance depends upon the theoretical yield and actual yield of the substance.
While theoretical yield of substance depends upon the moles of desired reactants and limiting reactant.
