Which technique is used to separate different pigments from an extract of flower petals? |
|
Answer» Explanation: Different pigments from the extracts of flower PETALS – chromatography. Chromatography is a TECHNIQUE of separation of substances which are very CLOSE in their molecular WEIGHT but differ in their molecular sizes. Since pigments from flower petals will be very similar in their components, it is EXPECTED that their molecular weights will also be similar. But they have different molecular sizes as an inherent property. Thus chromatography will be able to separate these pigments. |
