NaOH Concentration Determination via Titration

Vocabulary flashcards related to determining NaOH concentration using titration.

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 being determined 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 lab equipment used to accurately dispense variable amounts of a liquid, especially in titrations.

Erlenmeyer flask

A type of flask with a flat bottom, a conical body, and a cylindrical neck used to hold and mix solutions.

Meniscus

The curved surface of a liquid in a container. Read the buret at eye level at the bottom of the meniscus.

Fenolftaleïne

An indicator used in titrations that 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, another way to express concentration. It represents the mass of solute per 100 mL of solution.

Indicator

A substance that changes color to signal the endpoint of a titration.
