Carbon dioxide is not a pollutant but a naturally occurring, beneficial trace gas in the atmosphere. For the past few million years, the Earth has existed in a state of relative carbon dioxide starvation compared with earlier periods.
Description. When carbon dioxide reacts with water a weak acid is formed. Carbon dioxide is present in exhaled breath. Observing a colour change using an acid-base indicator shows the reaction between carbon dioxide and water.When carbon dioxide reacts with water a weak acid is formed.Carbon dioxide present in exhaled air is blown into a flask containing an indicator sensitive to small changes of pH in the appropriate region of the pH scale, and the consequent colour changes observed and recorded.escription.
