Titrations

Front

What is a titration?

Back

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

Front

What is the purpose of an indicator in a titration?

Back

An indicator is a substance that changes color at a specific pH level, signaling the endpoint of the titration.

Front

What does it mean when phenolphthalein turns bright pink during a titration?

Back

It indicates that the solution is basic (pH greater than 7).

Front

What is the pH range of acids?

Back

Acids have a pH less than 7.

Front

What is the pH range of bases?

Back

Bases have a pH greater than 7.

Front

What is the endpoint of a titration?

Back

The endpoint is the point at which the indicator changes color, signaling that the reaction is complete.

Front

What is the formula for calculating molarity (M)?

Back

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

Front

If 25 mL of 0.05 M HCl neutralizes 34.5 mL of NaOH, how do you find the concentration of NaOH?

Back

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

Front

What is a strong acid?

Back

A strong acid is an acid that completely dissociates in solution, releasing all of its hydrogen ions.

Front

What is a strong base?

Back

A strong base is a base that completely dissociates in solution, releasing all of its hydroxide ions.
