Question

• the technique used here to separate photosynthetic pigments is called ______________. a. thin layer chromatography b.electrophoresis c.paper chromatography d.x - ray chrystalography

Explanation:

Paper chromatography is a common method used to separate photosynthetic pigments. It works based on the different solubilities and affinities of the pigments for the paper (stationary phase) and the solvent (mobile phase). Thin - layer chromatography uses a thin layer of adsorbent (like silica gel) instead of paper. Electrophoresis separates molecules based on their charge and size in an electric field, which is not relevant for pigment separation here. X - ray crystallography is used to determine the three - dimensional structure of crystals, not for separating pigments.

Answer:

c. paper chromatography
