ASAP! According to the lab introduction in your laboratory manual, the equation for sodium
carbonate dissolving in water is:
NaCO3 + 2H,
02Na+ + 2OH- + H2CO3
When this process occurs, sodium carbonate does not 100% separate into ions.
There is always some sodium carbonate in solution.
Based on this reaction, explain whether Sample A or Sample B is most alkaline and
why.

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?
