Question
Why is it important to determine the percent recovery for chemical processes? In addition to considering its importance in the chemical laboratory, consider its importance to a chemical company 1. a. What properties must a solid have for the water displacement method to be useful? b. Another way of determining the volume of solid makes use of the fact that the difference in the mass of an object determined directly and suspended in water is the mass of the water displaced by the object. Division of this mass by the density of water gives the volume of the water displaced and therefore the volume of the object Would this method have any advantages over the water displacement method used in this experiment?Explanation / Answer
ANSWER 1 :- It is important to determine the percent recovery for chemical process because it gives you a way of comparing how much product you should have gotten from running a reaction against how much you actually got.
(a) Property must a solid have for the water displacement method to be useful is :- It must be at least as dense as water. It must not be soluble in water or chemically react with water.
(b) Yes, this method has advantage because this method makes it possible to determine the density of wood sponges and other materials that are "directly and suspended," in water. It is more efficient for these types of materials than the standard water displacement method (m/v1-v2). And so this method is useful.
