The following neutralization reaction occurs in the classroom.
HCl  +  KOH  -->  H₂O  +  KCl
If a student uses 25.0 mL of a 0.5M solution of KOH, what is the molarity of the acid if the is 15.0mL of acid neutralized?

• 0.8M
• 1.2M
• 12.5M

What is the main purpose of acid-base titrations?

• To test if reactants react.

• To calculate the concentration of unknown analyte.

• To calculate the concentration of known analyte.

• To test quality of reactants.

What is an equivalence point?

• It is the point when enough analyte has been added.

• It is the point when the amount of added titrant is equal to the amount of analyte in the solution.

• It is the point when the volume of titrant is equivalent the volume of analyte.

• It is the point when the concentration of titrant added is equivalent to the volume of analyte.
