The amount of lactic acid, HCa Hg 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 (9) + 20H (ag) 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 107 s for a current of 15.6 mA to reach the endpoint. How many grams of lactic acid (a monoprotic acid) were present in the sample?

5:15 1 ull 4G Discussion Assignment #6 O o o INFO DISCUSSION Discussion Assignment #6 Due:Wednesday, 14 Oct 2020, 3:00 PM In titration, one solution is added to another solution until a chemical reaction between the components in the solutions has run to completion. The solution being added is called the titrant, and we say that it solution. The completion of the reaction is usually shown by a change of color caused by a substance called an indicator. used titrate the other A typical titration proceeds in the following way. A specific volume of the solution to be titrated is poured into an Erlenmeyer flask. For example, 15.0 mL of a sulfuric acid solution of unknown concentration is added to a 250 mL Erlenmeyer flask. An indicator is then added to the flask, which changes color when the reaction is complete. The titrant in this example is potassium hydroxide, having a concentration of 0.121 M. The titrant is added to a buret. After slowly adding the titrant to the flask, the reaction…
