NaOH Concentration Determination by Titration

Flashcards for Chemistry Practicum on NaOH Concentration Determination

Titration

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

Buret

A graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations.

Erlenmeyer Flask

A conical flask with a flat bottom, used for mixing and titrating liquids.

Phenolphthalein

A chemical indicator that is colorless in acidic solutions and pink in alkaline solutions, used in titrations.

Molarity (mol/L)

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

NaOH

Sodium hydroxide, a strong base whose concentration is being determined through titration with HCl.

HCl

Hydrochloric acid, a strong acid used as a titrant to determine the concentration of NaOH.

Titration Endpoint

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

Volumetric Material

Laboratory equipment designed for accurate measurement of volume, such as burets, pipettes, and volumetric flasks.

m/V%

Mass/volume percentage concentration, expresses the mass of solute per 100 mL of solution.
