Whenever a mixture of gases is allowed to come in contact with a particular adsorbent under the same conditions, the more strong adsorbate is adsorbed to greater extent irrespective of its amount present, e.g. H2O is adsorbed to more extent on silica gel than N2 and O2. This shows that some adsorbates are preferentially adsorbed. It is also observed that preferentially adsorbable adsorbent can displace a weakly adsorbed substance from the surface of an adsorbent.
Q.
Activated charcoal is prepared by
  • a)
    Heated charcoal with steam so that it becomes more porous
  • b)
    Adding Ca3(PO4)2 to charcoal
  • c)
    Adding impurity to charcoal
  • d)
    Reacted with conc. HNO3
Correct answer is option 'A'. Can you explain this answer?
