The correct order of increasing (\left[\mathrm{H}_3 \mathrm{O}^{+}\right])in the following aqueous solutions is
Options
- A(0.01 \mathrm{M} \mathrm{H}_2 \mathrm{~S} < 0.01 \mathrm{M} \mathrm{H}_2 \mathrm{SO}_4 < 0.01 \mathrm{M} \mathrm{NaCl} < 0.01 \mathrm{M} \mathrm{NaNO}_2)
- B(0.01 0.01 \mathrm{M} \mathrm{NaNO}}_{2} \lt 0.01 \mathrm{M} \mathrm{H}}_{2} 0.01 \mathrm{M} \mathrm{H}}_{2} \mathrm{SO}}_{4})
- C(0.01 \mathrm{M} \mathrm{NaNO}_2 < 0.01 \mathrm{M} \mathrm{NaCl} < 0.01 \mathrm{M} \mathrm{H}_2 \mathrm{~S} < 0.01 \mathrm{M} \mathrm{H}_2 \mathrm{SO}_4)
- D(0.01 \mathrm{M} \mathrm{H}_2 \mathrm{~S} < 0.01 \mathrm{M} \mathrm{NaNO}_2 < 0.01 \mathrm{M} \mathrm{NaCl} < 0.01 \mathrm{M} \mathrm{H}_2 \mathrm{SO}_4).
Correct answer
C. (0.01 \mathrm{M} \mathrm{NaNO}_2 < 0.01 \mathrm{M} \mathrm{NaCl} < 0.01 \mathrm{M} \mathrm{H}_2 \mathrm{~S} < 0.01 \mathrm{M} \mathrm{H}_2 \mathrm{SO}_4)
Step-by-step solution
is strong acid having on hydrolysis gives alkaline solution of . is neutral and is weak acid.
