Acid–base titration

Assignments

  1. A 25.0 mL HCl sample reacts with 20.0 mL of 0.100 mol/L NaOH. Find the HCl concentration.
  2. Why might the indicator’s colour change occur slightly away from the equivalence point?
  3. If you add base beyond the endpoint, how will your calculated acid concentration change? Explain.
