Question

Given below is a column of adsorbent in which the mixture of compounds $A+B+C$ is placed. When the solvent is poured through the column, the components are separated depending upon the degree of adsorption. Which of the given statements is correct?

• A. $A$ is the most weakly adsorbed component hence remains near the top
• B. $A$ is the most strongly adsorbed component hence remains near the top
• C. $C$ is the most strongly adsorbed component hence is found near the bottom
• D. $B$ is the most strongly adsorbed component hence is found in the centre of the column

Answer 1

Answer: (B)

The most strongly adsorbed component is present in the band near the top while the weakly adsorbed constituent is found near the bottom.
