Answer to Question #96328 in General Chemistry for harpreet

Question

describe two source of error that may occur during decantation process?

Answer 1

There can be different types of error in decantation experiment:

1. The process of settling down of particles may require much more time than prescribed time(say 5 minutes).

2. The liquid or the upper layer of decantation process may not be completely extracted while the process. So,sometimes a test tube at $45\degree$ is used.

3. The filtrate may contain impurities of the other or settled phase ,so mass percentage of various components may change
