Question description

4. Vinegar contains acetic acid, CH3COOH. You can determine the mass of acetic acid in a vinegar sample by titrating with NaOH of known concentration. The reaction is: - CH2COOH(aq) + NaOH(aq) yields CH3COONa(aq) + H2O(l) a. if you find that 25 mL sample of vinegar requires 41.33 mL of a .953 M solution of NaOH for titration to the equivalence point, how many grams of acetic acid are there in the vinegar sample? b. What is the molar concentration of the acetic acid in the vinegar?
