CHXI07:EQUILIBRIUM

314390 Assertion :
Water acts as levelling solvent for various acids.
Reason :
Levelling effect of water is due to its high dielectric constant and strong proton accepting tendency.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.

314391 Which equilibrium can be described as an acid base reaction using the Lewis acid-base definition but not using the Bronsted-Lowry definition?

1 \(2 \mathrm{NH}_{3}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightleftharpoons 2 \mathrm{NH}_{4}^{+}+\mathrm{SO}_{4}^{2-}\)
2 \(\mathrm{NH}_{3}+\mathrm{CH}_{3} \mathrm{COOH} \rightleftharpoons$$\mathrm{NH}_{4}^{+}+\mathrm{CH}_{3} \mathrm{COO}^{-}\)

314392 Assertion :
\(\left[\mathrm{Al}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{3+}\) is a stronger acid than \(\left[\mathrm{Mg}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{2+}\).
Reason :
Size of \(\left[\mathrm{Al}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{3+}\) is smaller than \(\left[\mathrm{Mg}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{2+}\) and possesses more effective nuclear charge.
