NaOH Concentration Determination via Titration

Vocabulary flashcards for understanding the key terms and concepts in the NaOH concentration determination experiment.

Titration

A technique 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 the experiment.

HCl

Hydrochloric acid, the titrant used to react with the NaOH solution.

Buret

A piece of lab equipment used to accurately dispense variable amounts of a solution (titrant).

Erlenmeyer flask

A type of laboratory flask with a flat bottom, a conical body, and a cylindrical neck. Used to contain the analyte during titration.

Indicator (Phenolphthalein)

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

Molarity (mol/L)

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

Volume (mL)

The amount of space occupied by a substance.

Endpoint

The point in a titration where the indicator changes color, signaling the completion of the reaction is near.

M/V%

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

Pipet

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

Maatkolf

Volumetric flask.

Pipetpomp

Pipette pump.
