pH+scale

=pH Scale= The pH scale is a logarithmic measure of the concentration of hydrogen ions. It is used to measure the acidity or basicity of a substance. It has a range of 1 to 14, with one being the most acidic and fourteen being the most basic. pH paper uses colors to identify the pH of solutions. =History of the pH Scale= Soren Peter Lauritz Sorenson in 1909 defined pH as a logarithmic measure of hydrogen ion concentration. =Application of the pH Scale= The pH scale is good for measuring the acidity or how basic a solution is. The pH scale is mainly used in scientific experiments. It is also useful when trying to neutralize a solution. Knowing the rating of a solution will help you to stay away from harmful substances. For example, if using an exfoliant for your face you would not want to use one with a pH of 2, but of 6. 6 is closer to neutral, which means that it is a weak acid and will not case much harm or discomfort. =References=
