Controlling the amount of acid or base, referred to as pH, of our water is a very important task for civil engineers. For example, water with a pH of 5.0 or below will be corrosive and destroy pipes in your home. Water with a high pH of 8.0 or more will forma scale and start to clog pipes and form scale on sinks and tubs. Materials, such as activated granular charcoal is used to control waters pH as well as remove harmful substances from the water. This lab demonstrates the change in the pH curve when granular activated carbon is added during the acid base titration.
