NaOH Titration Flashcards

Flashcards for NaOH concentration determination through titration.

Titration

The determination of the concentration of sodium hydroxide by titration with a standardized 0.10 mol/L HCl solution.

Volumetric Material

Use of volumetric material like a volumetric flask, pipette, pipette pump, and burette

Standardized Solution

A solution with a precisely known concentration, used in performing titrations.

Burette

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

Statief (Stand)

Used to hold the Erlenmeyer flask during titration.

Erlenmeyer Flask

A flask with a wide, flat bottom and a conical body, useful for swirling liquids during titration.

Pipette

A piece of laboratory glassware used to accurately measure a specific volume of liquid.

Phenolphthalein

A chemical indicator that changes color near the equivalence point of an acid-base titration.

Equivalence Point

The point in a titration where the amount of titrant added is chemically equivalent to the amount of analyte in the sample.

Initial Buret Reading

Record the initial buret reading before titration.

Final Buret Reading

Record the final buret reading after titration.

Volume of HCl Added

Calculate the volume of HCl used by subtracting the initial buret reading from the final buret reading

Average Volume

Calculate the average volume of HCl used from multiple titrations

Concentration Calculation

Calculate the concentration of Sodium Hydroxide using the average volume of HCl used
