WebbReading the pH scale. The pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution. WebbIt is a relative measure and the pH scale is used to measure how acidic or basic a solution is. The scale starts at 0 and goes to 14. From 0 to 6 is acidic, 7 is neutral and from 8 to 14 is basic. Some examples of what this means in real life are: a car battery has a pH of 0 and is very dangerous if touched or ingested WebbA pH measurement system consists of three parts: a pH measuring electrode, a reference electrode, and a high input impedance meter.
