Question

Question 28 1 points Given below is a diagram of separation of two components of a mixture in a chromatographic column. From the diagram inter which component has lesser afinity to the stationary pha Mobile phase Component w Component Component Component

Answer 1

Ansas The components of mixture in column chromatography travel at different rate: Components having lower affinity to stationary phase travel fast & are renched fast whereas components having high affinity to stationary phase trand slawer & are eleted out last. Mobile phase & mixture of components X,Y, ZW is introduced from top of cdumne Since component Y is at down as compared to X,Y,Z. - Mobile phase 7 component w -Component X 7 component Z t Component Y le at has travel tast er as composed to other campaments. Hence, it has least affinity for Stationary phase Component Y is right answer. on the more yet to right ans wes (Y), P аng pХ

first Ansaq The three options are correct. Spots of coloulless compounds are invisible to eyes. (True). Spots of colourless compounds can be detected by putting plate under or light.
