3-Methylbutanoic (or isovaleric) acid is a weak organic acid with an unpleasant odourand occurs in trace amounts in foods such as cheese and soy milk. Like other smallcarboxylic acids, it is used to make pleasant smelling esters that are used inperfumes, cosmetics, and food additives.3-methylbutanoicacidThe K, of 3-methylbutanoic acid is 1.70x10-5. In Part A, a 15.00 mL aliquot of a 0.155 mol L-1 3-methylbutanoic acid solution was titrated to its equivalence point with 11.7 mL of 0.198 molL-1NaOH solution. At the equivalence point, all of the weak acid, 3-methylbutanoic acid, is converted to its weak conjugate base, 3-methylbutanoate.What is the pH at this equivalence point?6.9574.7708.8555.145O 9.230
