Question

3) The following plot shows two titration curves, each representing the titration of 50.00 mL of 0.100 M acid with 0.100 M NaOH. Use this graph for question 3a. [12 pts] 14 10 3 6 4 2 0 0 200 40.0 60.0 30.0 100.0 ml of 0.100 M Nadded a. i) Which point, a-d, represents the equivalence point for the titration of a weak acid? [2 pts] ii) Which point, a-d, represents the equivalence point for the titration of a strong acid? [2 pts] iii) Define what is meant by the equivalence point. [2 pts] b) When titrating a weak base with a strong acid, approximately where would the pH be observed when reaching the equivalence point? [2 pts) c) What are the products formed at the equivalence point when titrating a strong acid with a strong base? [3 pts) A. salt and water B. the solution is neutral, so water only C. no products are formed
