NaOH Concentration Determination via Titration

Vocabulary flashcards related to the determination of NaOH concentration using titration with a standardized HCl solution.

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, a strong acid used as the titrant to determine the concentration of NaOH.

Buret

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

Erlenmeyer flask

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

Pipet

A laboratory tool used to accurately measure and transfer a fixed volume of liquid.

Fenolftaleïne

An acid-base indicator that is colorless in acidic solutions and pink in basic solutions; used to detect the endpoint of the titration.

Indicator

A substance that changes color depending on the pH of the solution, used to signal the endpoint of a titration.

Endpoint

The point in a titration where the indicator changes color, indicating that the reaction is complete.

Molarity (mol/L)

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

m/V%

Mass/volume percentage, expressing the concentration of a solution as the mass of solute per 100 mL of solution.
