Titration of NaOH with HCl

Vocabulary flashcards for the NaOH concentration determination lab.

Titration

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

NaOH

Chemical formula for Sodium hydroxide. Used in this experiment, and the goal is to determine the concentration.

HCl

Chemical formula for Hydrochloric acid. A 0.10 mol/L solution is used as the titrant in this experiment.

Buret

A piece of laboratory glassware used to accurately dispense variable amounts of a chemical solution; used in titration.

Erlenmeyer flask

A type of laboratory flask with a flat bottom, a conical body, and a cylindrical neck; used to hold the solution being titrated.

Phenolphthalein

A chemical indicator used in titrations. It is colorless in acidic solutions and pink in basic solutions.

Indicator

A substance that changes color in response to a chemical change (e.g., pH change) within a solution.

Titration Calculation

Calculations are performed to determine the concentration of NaOH in mol/L and m/V%.
