Titration Flashcards

Flashcards for NaOH concentration determination by titration.

Titration

A lab technique used to determine the concentration of a solution.

NaOH

Sodium hydroxide, the substance whose concentration is being determined.

HCl

Hydrochloric acid, a solution with a known concentration (0.10 mol/L) used in the titration.

Buret

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

Erlenmeyer flask

A flask with a conical base and a cylindrical neck, used to hold liquids during a titration.

Phenolphthalein

An indicator used to detect the endpoint of the titration (colorless).

Endpoint

The point in a titration where the indicator changes color, signaling the completion of the reaction.

Molarity (mol/L)

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

m/V%

Another way to express concentration, mass per volume percentage.

Titration Calculation

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