Percent Yield vs. Percent Recovery: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Percent Yield measures the efficiency of a chemical reaction, comparing the actual product obtained to the theoretically expected yield. Percent Recovery assesses the amount of a substance recovered in a purification process, often from a crude mixture.
Key Differences
Percent Yield represents the efficiency of a chemical reaction, indicating how much of the theoretical product was actually obtained. Percent Recovery, on the other hand, refers to the amount of material recovered from a mixture or a process, compared to the initial quantity before the process began.

In chemical synthesis, Percent Yield is crucial for determining how close the experimentally obtained result is to the predicted outcome. Percent Recovery is important in purification processes, where it shows the extent to which the desired substance has been isolated from contaminants or other components.
