The strength of an aqueous NaOH solution is most accurately determined by titrating: (Note: consider that an appropriate indicator is used)
  1. Aq.NaOH in a pipette and aqueous oxalic acid in a burette
  2. Aq.NaOH in a burette and aqueous oxalic acid in a conical flask
  3. Aq.NaOH in a burette and concentrate H2SO4 in a conical flask
  4. Aq.NaOH in a volumetric flask and concentrated H2SO4 in a conical flask

Solution

Oxalic acid is a primary standard solution while H2SO4 is a secondary standard solution.

Titration is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte. A reagent, termed the titrant or titrator, is prepared as a standard solution of known concentration and volume.
