Titration of NaOH Concentration

Vocabulary flashcards about the concepts, materials, and procedures for determining NaOH concentration by titrating with HCl.

Titration

A technique used to determine the concentration of a solution (analyte) by reacting it with a solution of known concentration (titrant).

NaOH

Sodium hydroxide, a strong base whose concentration is determined through titration in this experiment.

HCl

Hydrochloric acid, the titrant used in this experiment with a known concentration of 0.10 mol/L.

Buret

A piece of laboratory glassware used to accurately dispense variable amounts of liquid during a titration.

Erlenmeyer flask

A type of flask with a flat bottom and conical body, used to hold the analyte during titration.

Phenolphthalein

An indicator dye that changes color depending on the pH of the solution; it is colorless in acidic solutions and pink in basic solutions.

Molarity (mol/L)

A unit of concentration, defined as the number of moles of solute per liter of solution.

m/V%

Mass/volume percent concentration, expressed as the mass of solute per 100 mL of solution.
