During increased body activity the CO 2 content of blood raises. It combines with water to form carbonic acid in the blood. This lowers the pH, which increases the heart be..
The pH Scale
The strength of acids and bases can be expressed in terms of the concentration of the hydronium ions or hydroxyl ions in a solution. The concentration of hydronium ions in a solution can be expressed as moles of hydronium ions per litre of solution. This is expressed by a term called 'pH'..
