Acid-Base Titration Quiz

True or False: A burette is typically used to deliver the titrant solution during acid-base titration.

True or False: Erlenmeyer flasks are preferred over beakers in titrations due to their narrower necks, which minimize evaporation.

What is the equivalence point in a titration?

• The point where the pH is neutral (pH 7)

• The point where the amount of titrant added exactly neutralizes the analyte

• The first visible color change of the indicator

• The halfway point of the titration

Which piece of equipment is used to accurately measure 10 mL of HCl for a titration?

• Beaker

• Volumetric Pipette

• Burette

• Graduated cylinder

Which of the following is commonly used as a primary standard in acid-base titration?

• Hydrochloric acid (HCl)

• Sodium hydroxide (NaOH)

• Potassium hydrogen phthalate (KHP)

• Sulfuric acid (H₂SO₄)

What is the purpose of an acid-base titration?

• To measure the pH of a solution

• To determine the concentration of an unknown acid or base

• To mix an acid with a base to form a salt

• To identify the color change in an indicator

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

• To neutralize the acid and base

• To determine the exact volume of the titrant

• To signal the endpoint of the titration through a color change

• To increase the reaction rate
