Question

What does a percent yield of 25% tell you about Aspirins idenity and purity? What can you determine?

Expert Solution

Step 1

Introduction

In chemistry, the percent yield is a measure of the efficiency of a chemical reaction, expressed as the percentage of the theoretical yield that is actually obtained in a laboratory experiment. The theoretical yield is the amount of product that would be produced if the reaction went to completion under ideal conditions.

The percent yield is calculated as follows:

$P e r c e n t y i e l d = (\frac{A c t u a l y i e l d}{T h e o r e t i c a l y i e l d} \times 100) %$

where actual yield is the amount of product obtained in the experiment, and theoretical yield is the amount of product that would be obtained if the reaction went to completion
