Question

name the technique to separate: 1.butter from curd, 2.salt from seawater,3.comphor from salt?​

Answer 1

Answer:

1) butter from curd - centrifugation

2) salt from seawater - evaporation

3) camphor from salt - sublimation

Answer 2

Answer:

1.Centrifugation

2 Evaporation

3.Sublimation

Explanation:

1. 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.

2.You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid.

3.Butter can be separated from curd by the process of Centrifugation. The principle behind this process is that the denser particles are forced to the bottom and the lighter particles stay at the top when spun rapidly.
