The amount of lactic acid, HC3H;O3, produced in a sample of muscle tissue was analyzed by its reaction with a hydroxide ion. A hydroxide ion was produced in the sample mixture by electrolysis. The cathode reaction was 2H2O(1) + 2e¯ –→ H2(g) + 2OH¯(aq) A 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 121 s for a current of 12.6 mA to reach the endpoint. How many grams of lactic acid (a monoprotic acid) were present in the sample? g
