The pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. It is a measure of the acidity or alkalinity of a solution. The greater the concentration of H+ the more acidic the solution and the lower the pH. The pH measurement is used in a wide variety of applications: agriculture, wastewater treatment, industrial processes, environmental monitoring, and research and development. The pH is very important in our digestive system. In the stomach, hydrochloric acid is secreted as food enters the stomach. It turns the pH of the stomach between 1 and 3. This pH is important for the activation of the enzyme pepsin, which helps in the digestion of protein in food. Read the presentation for more promising content.
