Answer 2

Common mixtures and their separation techniques

Explanation:

We will discuss sand in water, oil in water, and salt in water mixtures one by one.

1. Sand in water - Filtration:

• Sand can be easily separated from the water just by Filtering it.
• You need to put the mixture into a filter to do it, and it will be easily separated.

2. Oil in water - Separating funnel:

• These two are immiscible liquids that are only separated by using a separating funnel.
• The funnel has a stopper and water beneath the oil is poured down through it, and thus they are separated.

3. Salt in water - Evaporation:

• It is extremely easy to separate although it doesn't seem to.
• You need to boil the saline or saltwater in a pan, and the water will be evaporated and salt will be left behind in the pan.
• This method is used in extracting salt from the oceans.
