Calculate the ph when 1.73 g of ch3coona (fw = 82.03 g/mol) is added to 22 ml of 0.500 m acetic acid, ch3cooh. ignore any changes in volume. the ka value for ch3cooh is 1.8 x 10-5.

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?
