Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the role of pKa in choosing an indicator?

  • The range of color change of the indicator.
  • The temperature stability of the indicator.
  • How quickly the indicator changes color.
  • The relationship between pH at equivalence point and color change.

💡 Hint: Consider what pKa represents in relation to the equilibrium.

Question 2

Is methyl orange a suitable indicator for strong acid-weak base titrations?

  • True
  • False

💡 Hint: Think about what pH range you'd expect during such a titration.

Challenge Problems

Push your limits with challenges.

Question 1

You're performing a titration of acetic acid (a weak acid) with sodium hydroxide (a strong base). What indicator would you choose, and why?

💡 Hint: Consider the nature of the acid and base involved.

Question 2

During a titration of hydrochloric acid (strong acid) with ammonia (weak base), you notice the equivalence point is difficult to determine. What could be the problem?

💡 Hint: Think about the characteristics of the weak base and the expected pH ranges.
