Question

7. Iodine & sand mixture can be separated using sublimation technique. Based on difference in which physical property the separation takes place Difference in particle size Ability to sublime Difference in density Difference in solubility

Answer 1

Answer:

Sublimation is the process of transition of a substance from the solid to the gaseous state without passing through the liquid state. To separate mixtures that contain a sublimate with volatile component from a non-sublimate impurity, the sublimation process is used.

Explanation:

The remaining components of the mixture are salt and sand. Salt is soluble in water and sand is a non-water soluble substance that can be separated by the process of filtration. The insoluble sand remains in the filter paper while the filtrate contains the dissolved salt.

Answer 2

sand particle are large and iodine particle are small make it easy to be separated by sublimation
