(lit) camphor from salt.​

Answer 1

Answer:

hii mate...

1. The mixture of two miscible liquids such as kerosene and petrol whose boiling points differ by more than 25°C can be easily separated by the technique of simple distillation. The separation is based upon the principle that the boiling point of more volatile (low building liquid of the mixture.
2. i) Butter from curd can be separated by the technique of centrifugation. (ii) Salt from sea water can be separated by the technique of crystallization or by the evaporation. (iii) Camphor is sublimable but salt is not. So, camphor can be separated from salt sublimation technique.
