A student evaporated the remaining brown solution from Question 1 and weighed the mass of the dried product. Is it possible to determine the percent yield from in the experiment described in Question 1? Why or why not? Would this be different is there was a different limiting reagent?
(Consider the following observations: an unknown quantity of zinc was mixed with an unknown quantity of iodine in a test tube. Water and acetic acid were added and the contents of the tube were shaken for 20 minutes. After this time the solution in the tube was brown with no solids remaining in the solution. Agitating the tube for an additional 10 minutes produces no lightening of the color of the solution. ) This was the story from question 1.
