Vocabulary flashcards for Chemistry Titration Lab

Titration

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

NaOH

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

HCl

Hydrochloric acid, the titrant in this experiment, with a known concentration of 0.10 mol/L.

Buret

A piece of lab equipment used to accurately dispense a variable amount of liquid, used to deliver the HCl titrant.

Erlenmeyer flask

A type of flask used to hold the analyte (NaOH) during the titration process.

Phenolphthalein

A chemical indicator used to signal the endpoint of the titration by changing color (in this case, becoming colorless).

Endpoint

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

Molarity (mol/L)

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

Volume (mL)

The amount of space a substance occupies, measured in milliliters in this experiment.
