Question- In an experiment on identifying cations using paper chromatography, the cation that most strongly absorbs on the stationary phase
a) Shows a color spot near the top of the chromatography paper after completion of the rise of the solution through the capillary action.
b) Shows a color spot near the bottom of the starting position of the cations after completion of the rise of the solution through the capillary action
c) Moves the most rapidly in the rising column of solution on the chromatography paper though capillary action
d) Shows the smallest oval color spot after the spraying the paper with eth appropriate indicator
