The compound that will behave as an acid in $\mathrm{H_2SO_4}$ is
(a)$\mathrm{CH_3COOH}$
(b)$\mathrm{HNO_3}$
(c)$\mathrm{HClO_4}$
(d)$\mathrm{H_2O}$
Answer
Answer (as printed): C
Explanation
306 HClO4 behave as an acid in H2SO4 ,because HClO4 contain higher dissociation constant than that of H2SO4. HClO4, pKa, value -9 H2SO4 , pKa value -3, HNO3 , pKa value -1, CH3COOH , pKa value 4.7. pKa value of HClO4 > pKa value of H2SO4 CSIR DEC 2013]
