Percent Yield vs. Percent Recovery: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Published on December 7, 2023
Percent yield is the ratio of the actual yield to the theoretical yield in a chemical reaction, while percent recovery refers to the amount of material recovered compared to the original amount before processing or purification.

Key Differences

Percent yield in chemistry is a measure of the efficiency of a reaction, calculated by comparing the actual yield of a product to its theoretical yield. Percent recovery, on the other hand, is used to assess the effectiveness of a purification or extraction process by comparing the quantity of material recovered to the original amount.

The theoretical yield, against which percent yield is measured, is derived from stoichiometric calculations based on the limiting reactant. Percent recovery, however, involves measuring the amount of a specific substance recovered after a process like extraction, distillation, or purification.

Percent yield is crucial in evaluating the practical success of a chemical synthesis, indicating how close the experiment comes to the expected theoretical outcome. Percent recovery is important in processes where material is purified or isolated, indicating the extent to which the original material is successfully retrieved.

In laboratory settings, achieving a high percent yield is desirable for the efficiency of chemical reactions, whereas a high percent recovery is essential in processes where retaining the integrity of the original material is crucial, such as in pharmaceuticals.
