Question
Chapter 4, Problem 8Q
Interpretation Introduction
Interpretation:
The reason for the use of stemless funnels instead of long-stem funnels to filter hot solutions through filter paper should be explained.
Concept introduction:
The funnel is a tube that is narrow at the bottom but wide at the top. It is used to pour liquids or power through a small opening. It is generally made up of stainless steel, aluminium, glass or plastic. The material used to make funnels is chosen in such a way that it does not react with the other substances.
Following are some of the types of funnels:
- Filter funnels
- Thisle funnel
- Dropping funnel
- Buchner funnel
- Hirsch funnel
- Tullgren funnel
- Separatory funnel
