Question

State a method of separation of gas gas mixture containing two gases with different densities

Answer 1

Answer:

Separation of two gases by diffusion - definition

Separation of two gases by diffusion - definitionTwo gases is passed through a porous partition. Lighter gases diffuse more rapidly than heavier gases. The underlying principle is the difference in the densities of gases.

Explanation:

example:

1. Two solid mixtures one of which - directly changes into vapour on heating.
2. Two solid mixtures one of which - dissolves in a - particular solvent and other does not.
3. A solid-liquid mixture containing - an insoluble solid in the liquid component.
4. A solid-liquid mixture containing - a soluble solid in the liquid component.
5. A liquid-liquid mixture containing - two immiscible liquids having different densities.
6. A liquid-liquid mixture containing - two miscible liquids having different boiling points.
7. A liquid-gas mixture containing - a gas dissolved in a liquid component.
8. A gas-gas mixture containing - two gases with different densities.
9. A mixture of different solid constituents - in a liquid constituent.

solutions:

1. Sublimation - Sublimable solid changes into vapour on heating and the non-sublimable solid is left behind, and they are separated.
2. Solvent extraction - The soluble solid dissolves in the solvent and the insoluble solid is left behind, and they are separated.
3. Filtration - insoluble solid is left behind in the filter.
4. Evaporation - The soluble solid is left behind while the liquid evaporates.
5. Separating funnel - Heavier liquid collects at the bottom layer, while the lighter liquid layers on the top in the funnel.
6. Fractional distillation - The liquid with a high boiling point remains in a distillation flask while the other one collects in the receiver.
7. Boiling - The gas escapes when the mixture is boiled, as the solubility of gas decreases with increase in temperature.
8. Diffusion - Lighter gas diffuses faster than heavier gas, the porous partition separates them.
9. Chromatography
