Paper 2 · Titration apparatus, indicators and obtaining pure crystals
A burette containing sodium hydroxide solution, NaOH(aq), is clamped above a conical flask containing dilute sulfuric acid, H2SO4(aq), with 2-3 drops of a solution Y added to the acid before the NaOH is run in from the burette. Name the analytical technique being carried out.
Model answer
titration
Also accepted: volumetric analysis, acid-base titration, quantitative analysis
Explanation: This is titration (volumetric/quantitative analysis): a measured volume of NaOH(aq) is added from a burette to a known volume of H2SO4(aq) until the reaction's end point is reached.
