Answer:
constituents of blood- centrifugation.
Reason-Centrifugal force is used to separate the components of blood – red bloodcells, platelets and plasma – from each other. The result is that the particles with different densities precipitate in layers.
chloroform and water- A mixture of chloroform and water taken in a separating funnel is mixed and left undisturbed for some time. The upper layer in the separating funnel will be of water and the lower layer will be that of chloroform (It is because water is lighter than chloroform).
separation of amino acids- Chromatography.
Reason-The amino acid that interacts strongly with silica will be carried by the solvent to a small distance, whereas the one with less interaction will be moved further. By running controls [known compounds ] alongside, it is possible to identify the components of the mixture.
mixture of acetone and ethyl alcohol-fractional distillation.
Reason-To separate a mixture of two or more visible liquids for which the difference in boiling points is less than 25K,fractional distillation is used.
hope this helps
