Grease spots from garments can be separated by a method of
The correct option is D Dissolution in a suitable solvent
Solvent extraction: It is the technique for the separation of a substance from a mixture by dissolving it in a solvent that will dissolve it but not dissolve another substance from the mixture.
When garments containing grease spots are dipped in soap water, The grease will be soluble in it.
These result in the separation of grease from cloth.
Dissolution in a particular solvent:
Dissolving the cloth containing grease in a particular solvent that can dissolve grease will result in the separation of grease from the cloth
Chromatography: It is the technique for the separation of a mixture based upon the principle of adsorption of the mixture on an adsorbent surface.
Every component in the mixture has a different adsorption rate.
This is not used in the separation of grease from cloth.
Sublimation: It is the process of conversion of a solid-state into a gaseous state of a substance without forming any intermediate state.
This is not used in the separation of grease from cloth.
Hence, option(b) and option(d) are correct.
