In the Limiting and Yield Lab, the idea of this particular lab is to identify the limiting
reactant and yield percentage. The limiting reactant is a reactant in a chemical reaction that
determines the amount of product produced. (Anne Marie Helmenstine Ph.D., ThoughtCo.)
Percent yield is calculated to be the experimental yield divided by theoretical yield multiplied by
100%. This is also known as percentage yield. The percent yield of a reaction measures the
reactions efficiency. It is the ratio between the actual yield and the theoretical yield. The
theoretical yield for a reaction is calculated based on the limiting reagent. This allows researchers
to determine how much product can actually be formed based on the reagents present at the
beginning of the reaction. The actual yield will never be 100 percent due to limitations.
(Boundless Chemistry Textbooks). If the limiting reactant of 0.3g Aluminum reacts with 3.5g of
Copper (II) Chloride, the theoretical yield will be 0.589 or more
