Question: The strength of an aqueous $\mathrm{NaOH}$ solution is most accurately determined by titrating :
(Note : consider that an appropriate indicator is used)
$\mathrm{Aq} . \mathrm{NaOH}$ in a volumetric flask and concentrated $\mathrm{H}_{2} \mathrm{SO}_{4}$ in a conical flask
$\mathrm{Aq} . \mathrm{NaOH}$ in a pipette and aqueous oxalic acid in a burette
$\mathrm{Aq} . \mathrm{NaOH}$ in a burette and concentrated $\mathrm{H}_{2} \mathrm{SO}_{4}$ in a conical flask
$\mathrm{Aq} . \mathrm{NaOH}$ in a burette and aqueous oxalic acid in a conical flask
