Answer:
You find a separatory funnel set up in a fume hood. There are clearly two visible layers. Describe a method you could use to determine which layer is the aqueous layer.
Explanation:
In the separating funnel, the liquid with less density exists at the top layer and the liquid with greater density will exist at the bottom layer.
To identify the aqueous layer, add a bit of water to the separating funnel.
Then, observe where the water will go and mix.
If it mixes with the bottom layer, then the bottom layer is the aqueous layer.
If water mixes with the top layer, then top layer is the aqueous layer.
A method we could use to determine which layer is the aqueous layer is by adding 2-4 drops of water in the separatory funnel.
Explanation:
- A separatory funnel is a glass apparatus used in labs to separate two immiscible liquids from each other.
- The two liquids will be present distinctly in form of two different layers one on the other.
- The liquid at the bottom is with higher density in comparison to the liquid layer at the top which is with lower density.
- It is mainly used to separate the layer of organic compounds from the aqueous layer.
- One way to determine the aqueous layer in the separatory funnel is to add 2-4 drops of water to the separatory funnel and observe in which layer the water drops get invisible that is mixed up.
- The layer in which water drop mixes will experience a small increase in its volume and that will be the aqueous layer.
- Water drops will not mix with the organic layer can be easily observed with eyes.
So, from this, we can conclude that a method we could use to determine which layer is the aqueous layer is by adding 2-4 drops of water in the separatory funnel.
