Hint:We are given a mixture of salt, sand and iodine and asked to select the best technique from the options given to separate these mixtures. Analyze the given mixture and its components and select the best technique.
Complete answer:
Given, a mixture of salt, sand and iodine. You are asked to select the best technique to separate these mixtures.We will check the properties of the components of the mixture.One component of the mixture is iodine. We know on heating, iodine changes from solid to gaseous state.
The other components are salt and sand. Salt is soluble in water whereas sand is not soluble in water. So sand and salt can be separated using the process of filtration.From the given options, sublimation is the best technique to separate these mixtures and in case of sublimation the solid changes directly from solid to gaseous state.
Hence, option B is correct.
Note:The options given are evaporation, distillation and solvent extraction. Evaporation is the process of changing a substance from liquid to vapour. Distillation is the process of separating two liquids which have different boiling points. Solvent extraction is the process in which the components are separated based on their solubility.
