For example, you can't spend more than 100% of your time playing basketball, no matter how much you love the sport; 100% is all the time you have, and there ain't no more. The theoretical maximum of 100% indicates that polymerase enzyme is working at maximum capacity. Why Is Percent Recovery More Than 100 For Recrystallization? This could be because other, unexpected reactions occur which dont produce the desired product, not all of the reactants are used in the reaction, or perhaps when the product was removed from the reaction vessel it was not all collected. Erin, thanks for the kind words. Solutions. The recovery for accepted range in analytical chemistry is 70-120%. The result is your percent recovery of that chemical for the procedure. Another way is to calculate the grams of products produced from the given quantities of reactants; the reactant that produces the smallest amount of product is the limiting reagent (approach 2). Multiply the result of your last calculation by 100. The cookie is used to store the user consent for the cookies in the category "Other. What is percentage recovery in analytical chemistry? The amount of acetanilide that will come out of solution is (5 0.53) or 4.47 g. The maximum percent recovery is then 4.47/5 = 0.89 or 89%. All it means is that the analytical method which is being followed "in letter and spirit" gives a positive error. The cookie is used to store the user consent for the cookies in the category "Other.
