NaOH Concentration Determination by Titration

Flashcards for Chemistry Titration Lab

Titration

A method to determine the concentration of a substance by reacting it with a solution of known concentration.

Buret

Equipment used to accurately dispense a known volume of liquid during titration.

Erlenmeyer flask

A flask used to hold the solution being titrated.

Indicator

A substance that indicates the endpoint of a titration, usually by a color change.

Standard solution

A solution of accurately known concentration.

Endpoint

The point in a titration where the reaction is complete, usually indicated by a color change.

Phenolphthalein

A weak acid that is colorless in acidic solutions and pink in basic solutions.

HCl

Hydrochloric acid, the titrant used to determine the concentration of the sodium hydroxide solution.

NaOH

Sodium hydroxide, the solution whose concentration is being determined.

Titration volume

The volume of titrant (HCl) added from the buret to reach the endpoint of the titration.
