Why is it important to know the temperature of the water when dealing with ions in an aqueous solution?

Water does not ionize at higher temperatures.

Water becomes very acidic when at low temperatures.

Temperature affects the concentration of water.

The ionization constant of water is usually given at 25 °C.

Water at a higher temperature will produce more ions than water at a lower temperature.

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?
