Waec Model Questions Vol1 2025 Chemistry Question 4
Practice practical question 4 from the 2025 Waec Model Questions Vol1 Chemistry examination. This question covers Mole Concept .
A student is performing a titration experiment to determine the concentration of hydrochloric acid (HCl) using a sodium hydroxide (NaOH) solution of known concentration. The balanced chemical equation for the reaction is: HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) (a) Describe the procedure the student would follow to carry out the titration, including the setup of apparatus and the indicators used. (b) If the student used 25.0 mL of HCl and titrated it with 0.1 M NaOH, and the endpoint was reached at 30.0 mL of NaOH solution, calculate the concentration of the hydrochloric acid solution. (c) Discuss possible sources of error in this experiment and how they could be minimized.
