(Note : consider that an appropriate indicator is used)
Select the correct option:
A
Aq. NaOH in a pipette and aqueous oxalic acid in a burette
B
Aq. NaOH in a burette and aqueous oxalic acid in a conical flask
C
Aq. NaOH in a burette and concentrated $\mathrm{H}_2 \mathrm{SO}_4$ in a conical flask
D
Aq. NaOH in a volumetric flask and concentrated $\mathrm{H}_2 \mathrm{SO}_4$ in a conical flask
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
