Water A change of 1 unit on a pH scale represents a 10fold change in the pH so that water with pH of 7 is 10 times more acidic than water with a pH of 8 and water with a pH of 5 is 100 times more acidic than water with a pH of 7 There are two methods available for the determination of pH electrometric and colorimetric methods Excessively high and low pHs can be detrimental for the use of water A high pH makes the taste bitter and decreases the effectiveness of the chlorine disinfection thereby causing the need for additional chlorine The amount of oxygen in water increases as pH rises LowpH water will corrode or dissolve metals and other substances Pollution can modify the pH of water which can damage animals and plants that live in the water 2alklanity The high levels of either acidity or alkalinity in water may be an indication of industrial or chemical pollution Alkalinity or acidity can also occur from natural sources such as volcanoes The acidity and alkalinity in natural waters provide a buffering action that protects fish and other aquatic organisms from sudden changes in pH For instance if an acidic chemical has somehow contaminated a lake that had natural alkalinity a neutralization reaction occurs between the acid and alkaline substances the pH of the lake water remains unchanged For the protection of aquatic life See Answer
