Recall that at the equivalence point of a titration:
Also, recall that:
Solving for Macid:
= 1.575 M
The distinctive odor of vinegar is due to acetic acid, CH3COOH, which reacts with sodium hydroxide in the following fashion:
CH3COOH(aq) + NaOH(aq)(l) + NaC2H3O2 (aq)
You may want to reference (Pages 149 - 153) Section 4.6 while completing this problem.
If 3.55 mL of vinegar needs 43.0 mL of 0.130 M NaOH to reach the equivalence point in a titration, how many grams of acetic acid are in a 1.60 qt sample of this vinegar?
