Assertion (A) The property of adsorption is shown to a great extent by solids than liquids. Reason (R) Solids like charcoal, silica can act as good adsorbents.

Options

  1. AA and R are correct and R is the correct explanation for A .
  2. BA and R are correct but R is not the correct explanation for A .
  3. CA is correct but R is incorrect.
  4. DA is incorrect but R is correct.

Correct answer

B. A and R are correct but R is not the correct explanation for A .

Step-by-step solution

Both Assertion and Reason are true but reason is not the correct explanation of Assertion. The property of adsorption is shown to a great extent by solids than liquids as extent of adsorption increases with surface area of adsorbent. Solids like charcoal, silica can act as good absorbents because of increased surface area.
