Acid-Base Titration Quiz

What is the purpose of adding an indicator in an acid-base titration?

• To increase the reaction rate

• To change the color when the acid and base are exactly neutralized

• To decrease the pH of the solution

• To act as a catalyst

What is the equivalence point in a titration?

• When the titrant is completely consumed

• When the pH of the solution reaches 7

• When the acid and base have exactly neutralized each other

• When the indicator changes color

What is titration primarily used for?

• To determine the pH of a solution

• To standardize an acid or base and determine its concentration

• To measure the volume of a solution

• To observe the color change in a reaction

What is the endpoint of a titration?

• When the titrant is added in excess

• When the indicator changes color

• When the pH of the solution is neutral

• When the analyte is completely consumed

What are the products of a neutralization reaction in a titration?

• Acid and base

• Water and salt

• Indicator and titrant

• Titrant and analyte
