NaOH Concentration Determination via Titration

Flashcards covering key vocabulary and concepts related to the determination of NaOH concentration via titration, including titration principles, equipment, and chemicals involved.

Titration

A technique used to determine the concentration of a solution by reacting it with a solution of known concentration.

Standard Solution

Solution of known concentration (HCl in this experiment) used in a titration to determine the concentration of an unknown solution.

Indicator

A substance (Phenolphthalein in this experiment) that changes color at or near the equivalence point of a titration.

Equivalence Point

The point in a titration where the acid and base have completely reacted, resulting in a neutral solution.

Buret

Laboratory glassware used to accurately dispense variable amounts of liquid; essential for precise titrations.

Pipet

Laboratory glassware used to accurately measure a fixed volume of liquid.

NaOH

Chemical formula for Sodium Hydroxide, the base whose concentration is being determined.

HCl

Chemical formula for Hydrochloric Acid, the standard solution used to titrate the NaOH.

Phenolphthalein

A colorless to pink pH indicator; turns pink in basic solutions and is colorless in acidic solutions.

m/V%

Expression of concentration as the mass of solute per volume of solution, expressed as a percentage.
