NaOH Concentration Determination via Titration

Flashcards for key concepts and procedures in determining NaOH concentration through titration.

Goal of the Practicum

Determination of the concentration of sodium hydroxide by titration with a standardized 0.10 mol/L HCl solution.

Research Problem

To determine the concentration of sodium hydroxide using titration with a 0.10 mol/L HCl solution.

Materials

Buret, statief, buretklem, 250 mL Erlenmeyer flask, 100 mL graduated cylinder, 10 mL pipet, funnel, white card.

Substances Used

Phenolphthalein, distilled water, NaOH solution, and 0.10 mol/L HCl solution.

Procedure

Add phenolphthalein to NaOH in Erlenmeyer flask, fill buret with HCl, titrate until colorless, record volumes, repeat 3 times, calculate average volume.

Calculations

Calculates the concentration of NaOH in the solution expressed in mol/L and m/V%.
