Titration Pre-Lab Flashcard

Front

What is titration?

Back

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

Front

What is a burette?

Back

A graduated glass tube used to deliver precise volumes of a liquid in titration.

Front

What does the term 'endpoint' mean in titration?

Back

The point at which the reaction is complete, often indicated by a color change.

Front

What is the purpose of using an indicator in titration?

Back

To signal the endpoint of the titration by changing color.

Front

What is phenolphthalein?

Back

A common acid-base indicator that turns pink in basic solutions.

Front

What is the formula to calculate molarity (M)?

Back

Molarity (M) = moles of solute / liters of solution.

Front

How do you calculate weight percent (% w/w)?

Back

Weight % = (mass of solute / total mass of solution) x 100.

Front

What is the significance of the color change in phenolphthalein during titration?

Back

It indicates the transition from acidic to basic conditions.

Front

What is the typical volume of vinegar used in a titration trial?

Back

10.00 mL.

Front

How do you determine the volume of NaOH used in a titration?

Back

By subtracting the initial burette reading from the final burette reading.
