Question

What purposes can funnels serve in the lab?

A) Support for filter paper during a gravity filtration
B) Assistance for pouring liquids into burets
C) Change the speed at which a solution drips
D) Help for transferring solid chemicals from weigh boats

Answer 1

Funnels serve purposes such as assisting in pouring liquids into burets, helping with transferring solid chemicals from weigh boats, and aiding in separating immiscible liquids in the lab.

Step-by-step explanation:

Funnels serve various purposes in the lab, including:

1. Assisting in pouring liquids into burets: Funnels are used to guide liquids into narrow-mouthed containers such as burets, ensuring accurate and controlled pouring.
2. Helping with transferring solid chemicals from weigh boats: Funnels can be used to transfer solid chemicals from weigh boats into other vessels or containers, preventing spillage and ensuring easy and controlled transfer.
3. Aiding in separating immiscible liquids: Separatory funnels are used to separate immiscible liquids by allowing them to form layers, which can then be separated using the stopcock at the bottom. This is commonly used in extraction processes to recover desired products from reaction mixtures.
