Question

3. Below is the titration curve of a weak acid and a strong base: a) Indicate the region of the graph is affected by buffering action? b) Locate and mark the location along with pH value where the acetic acid and the acetate ions concentration are approximately equal. c) Explain why the pH at the equivalence point is not 7. pH Equivalence point Volume NaOH added (ml) The pH titration curve of weak acid (CH3COOH) and strong base (NaOH)

Step 1

This region is where the pH remains relatively constant despite the addition of small amounts of strong base or acid. In the titration curve of a weak acid and strong base, this region occurs around the half-equivalence point. ** Show more…
