The amount of lactic acid, HC3H5O3, produced in a sample of muscle tissue was analyzed by reaction with hydroxide ion. Hydroxide ion was produced in the sample mixture by electrolysis. The cathode reaction is given below. 2 H2O(l) + 2 e− → H2(g) + 2 OH− (aq) Hydroxide ion reacts with lactic acid as soon as it is produced. The endpoint of the reaction is detected with an acid-base indicator. It required 104 s for a current of 13.1 mA to reach the endpoint. How many grams of lactic acid (a monoprotic acid) were present in the sample?

During an electrolysis experiment, the following species are present in solution: H+, CH3COOH, CH3COO-, Na+, SO42-, H2O. The lead electrode dipped in the solution serves as the anode. Why can't the polyatomic anion SO42- be oxidized in this experiment? because sulfur in this anion has its highest possible oxidation number of +6 because sulfur in this anion cannot give up any more electrons because SO42- cannot act as a reducing agent all statements above are correct
