NaOH Concentration Determination by Titration

Flashcards covering key vocabulary and concepts related to the titration of NaOH with HCl to determine its concentration.

Titration

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

NaOH

Sodium Hydroxide, a strong base whose concentration is being determined in this experiment.

HCl

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

Buret

A piece of lab equipment used to accurately dispense variable amounts of a liquid.

Erlenmeyer flask

A flask with a conical base and cylindrical neck used to mix or store solutions. Used during titration to hold the analyte.

Phenolphthalein

A pH indicator that turns colorless in acidic solutions and pink in basic solutions; used to determine the endpoint of the titration.

Endpoint

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

Molarity (mol/L)

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

m/V%

Mass/Volume percentage; expresses the concentration of a solution as the mass of solute per 100 mL of solution.
