Answer 1

Hello

Distillation is more advantageous than evaporation because with evaporation, we have more risk of losing the desirable substances inair due to heating it. or, this could lead to an impure solution that contains both substances.

chromatography is a process or technique to separate different colour components from a mixture.

The Advantages of Chromatography

Precise separation, analyses, and purification is possible using chromatography.

It requires very low sample volumes.

It works on a wide range of samples including drugs, food particles, plastics, pesticides, air and water samples, and tissue extracts.

Paper chromatography is a simplest type of chromatography.

I hope my answer will help you

Answer 2

Answer:

Distillation is more advantageous than evaporation because with evaporation, there is more risk at losing the desired substance to the air. or, this could lead to an impure solution that contains both substances.

technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.

Mikhail Tsvet and Early Column Chromatography

In the 1890s, column fractionation was developed as a technique to separate out the different components of petroleum. ... As a result, he named the technique “chromatography”; “chroma” from the Greek word for “colour”, combined with “graphy”, meaning writing or recording

Chromatography is based on the principle where molecules in mixture applied onto the surface or into the solid, and fluid stationary phase (stable phase) is separating from each other while moving with the aid of a mobile phas

Explanation:

All forms of chromatography work on the same principle. They all have a stationary phase (a solid, or a liquid supported on a solid) and a mobile phase (a liquid or a gas). The mobile phase flows through the stationary phase and carries the components of the mixture with it.
