What two physical properties allow a mixture separated by chromatography?

Answer: Option-1 (Solubility and Molecular polarity) is the correct answer. Explanation: Thin Layer Chromatography is employed to separate a mixture of non volatile compounds.

What physical property does centrifugation used to separate mixtures?

CENTRIFUGING is the process of separating a suspended solid from a liquid by whirling the mixture at high speed. SUBLIMATION is the physical property of some substances to pass directly from the solid state to the gaseous state without the appearance of the liquid state.

Can mixtures be separated using physical properties?

Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.

What are the advantages of evaporation?

Evaporation process benefits for foods and beverages. Beverage producers use evaporation processing to create concentrates (such as juice concentrates). Dairy producers use it to dry whey or lactose into powders, which can then be used in new products like infant formula or protein shakes.

Why is the solution not evaporated to dryness?

In many salt preparations its important not to completely dry the crystals because some might decompose on further heating. You can filter sea water to remove any debris and slowly evaporate the water by heating the filtrate in an evaporating dish until salt crystals start forming.

How do you evaporate a solution to dryness?

HOW DO YOU HEAT TO DRYNESS SAFELY? If a solution is left to stand, the solvent will slowly evaporate leaving the solids behind. If the solution is heated, the solvent will evaporate faster. Heating a solution until all the solvent has evaporated is known as heating to dryness.

Why is solution not heated to dryness for crystals?

Why is solution not heated to dryness to get crystals ? Ans. Heating the solution to dryness will not remove soluble impurities and crystals of very poor quality are obtained.

What happens when you cool a saturated solution?

If a saturated solution is cooled below a temperature at which the solution is prepared, then it will lead to a decrease in solubility of the solute. Again, if this solution is heated, the crystals would dissolve in the solution and no longer be visible.
