NaOH Concentration Determination by Titration

Flashcards for a chemistry lab experiment on determining NaOH concentration through titration.

Titration

A laboratory method to determine the concentration of an unknown solution using a solution of known concentration.

NaOH

Sodium hydroxide, the substance whose concentration is being determined in the experiment.

HCl

Hydrochloric acid, the titrant with a known concentration (0.10 mol/L) used to react with the NaOH.

Buret

A piece of laboratory glassware used to accurately dispense variable amounts of liquid, essential for titration.

Erlenmeyer Flask

A conical flask used to hold the solution being titrated (NaOH) and to which the titrant (HCl) is added.

Phenolphthalein

An acid-base indicator used to visually determine the endpoint of the titration (color change from pink to colorless).

Endpoint

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

Molarity (mol/L)

A unit of concentration expressing the number of moles of solute per liter of solution.

m/V%

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

Volumetric Material

Laboratory equipment designed for precise measurement of liquid volumes, such as burets, pipettes, and volumetric flasks.
