(a) The Potassium Permanganate solution is standardized by the prep room before it is used in this experiment? Why is it important that it is standardized prior to use? What would happen if it was not?
(b) Is an indicator required for titrations in which Potassium Permanganate is the titrant? Why or why not?
(c) What are possible sources of error in this experiment? How would each error affect the final result?

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?
