The correct order of increasing $\left[{\mathrm{H}}_3{\mathrm{O}}^{+}\right]$ in the aqueous solution is

• A

  $0.01{\mathrm{MH}}_2 \mathrm{S}<0.01{\mathrm{MH}}_2{\mathrm{SO}}_4<0.01\mathrm{MNaCl}<0.01{\mathrm{MNaNO}}_2$

• B

  $0.01\mathrm{MNaCl}<0.01{\mathrm{MNaNO}}_2<0.01{\mathrm{MH}}_2 \mathrm{S}<0.01{\mathrm{MH}}_2{\mathrm{SO}}_4$

   

• C

  $0.01{\mathrm{MNaNO}}_2<0.01\mathrm{MNaCl}<0.01{\mathrm{MH}}_2 \mathrm{S}<0.01{\mathrm{MH}}_2{\mathrm{SO}}_4$

• D

  $0.01{\mathrm{MH}}_2 \mathrm{S}<0.01{\mathrm{MNaNO}}_2<0.01\mathrm{MNaCl}<0.01{\mathrm{MH}}_2{\mathrm{SO}}_4$
