namotanity Tha sraph of pl NuOft for the eerant and the volume of titraet uasd at twe onervsa ea example is given below Dole the values anseurtrin olyy Equivalence poit 1 (m/L 1tran Eurvalence paint 2 mL itrant) 200 Half euwalence point 1 pH Hair equivalence point 2 pH 880 pKa1 pKa2 Molarity of phosphoric acid (mon 082 (3 points) For the unknown acid: (0) The titration curve data in two columns. (i) The graph of pli versus volume of titrant (iii) In the data box include the value of pka for the weak acid, the molarity sf the weak d and your gess of the identity of the weak acid Possible unknown weak acids from which to choose from are:

Explanation / Answer

Possible unknnown weak acids to choose from are,
Acetic acid, oxalic acid , Aniline hydrochloride
But looking from the titration curve the most probable answer would be Acetic acid, CH3COOH
