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 compounent 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)

A is the most strongly adsorbed compounent hence remains near the top

Answer 2

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