Titration

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 the purpose of a burette in titration?

Back

To accurately measure and dispense variable volumes of a titrant solution.

Front

What is the endpoint of a titration?

Back

The point at which the amount of acid and base are equal, indicated by a color change.

Front

What is a titrant?

Back

The solution of known concentration used in titration.

Front

What is the role of an indicator in titration?

Back

To signal the endpoint of the titration, usually through a color change.

Front

What is the formula to calculate molarity?

Back

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

Front

If 25.0 mL of 0.5M KOH is used to neutralize an acid, how do you find the molarity of the acid?

Back

Use the formula: M1V1 = M2V2, where M1 and V1 are the molarity and volume of KOH, and M2 and V2 are the molarity and volume of the acid.

Front

What is the significance of the color change in titration?

Back

It indicates that the reaction is complete and the endpoint has been reached.

Front

What is the typical volume range for a burette?

Back

Typically 50 mL, but can vary depending on the specific burette used.

Front

What is the difference between a strong acid and a weak acid in titration?

Back

Strong acids completely dissociate in solution, while weak acids only partially dissociate.
