NaOH Concentration Determination by Titration

Vocabulary flashcards for understanding the key terms and concepts in a titration experiment to determine the concentration of NaOH.

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; its concentration is being determined by titration in this practicum.

HCl

Hydrochloric acid; used as the titrant with a known concentration of 0.10 mol/L.

Volumetric Material

Equipment used for precise measurement of volumes, such as a volumetric flask, pipette, and burette.

Burette

A graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations.

Erlenmeyer Flask

A flask with a conical base and a cylindrical neck, used for mixing and titration.

Phenolphthalein

A pH indicator used in titrations; 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 percentage; a way to express concentration as the mass of solute per 100 mL of solution.
