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.
