Question

Write the method to separate the following mixtures:
1. Water and petrol
2. Wheat, grams and husk
3. Salt from salt solution
4. Camphor salt mixture​

Answer 1

Explanation:

this is the answer

Wheat, grams and husk

Answer 2

Answer:

Ans- 1.Use a separating funnel since the petrol floats above the water. ... Petrol and water are not soluble, so they will eventually separate. Since the petrol is lighter than the water, it will form a layer on top, and may be drawn off. Petrol will form at the top of water as it is not as heavy.

2.Winnowing is the process in which lighter husk are separated from heavier grains like wheat. In this method, the mixture is allowed to fall from a height. In this process husk which are lighter, blown out slightly far from grains.

3.Salt mixes well in water to form a clear salt solution. As we know, salt and water have different boiling points. Hence, we can use the "evaporation" technique to separate salt from salt solution. For this, one has to simply heat the salt solution till all the water boils and evaporates, and salt is left behind.

4.Sublimation is a technique used to separate the components of a mixture containing a sublimable volatile solid and a non-sublimable impurity. Therefore, the mixture of camphor and sodium chloride can be separated by the process of sublimation.
