Chapter 9, Problem 76E

Interpretation Introduction

Interpretation:

In the reaction of lead $\left(\text{II}\right)$ nitrate and aqueous potassium iodide where the collected yield of lead $\left(\text{II}\right)$ iodide is $\text{12}\text{.5}\text{g}$ and the theoretical yield is $\text{13}\text{.9}\text{g}$, the percent yield of lead $\left(\text{II}\right)$ iodide is to be calculated.

Concept introduction:

The percentage ratio of actual yield to theoretical yield is known as percent yield. When the actual and theoretical yield are same then the percent yield is $100\%$. The percent yield is always less than $100\%$. It can only increase when there is incomplete or complete reaction or sample loss during recovery.
