What is the PH scale? It is a scale to determine how acidic or basic a substance is. Ph stands for potential of hydrogen. It ranges from 0 to 14. If a substance is at 7 then it is neutral but if it is below that then it is acidic. Anything greater that 7 is basic. Each whole value below PH 7 is ten times more acidic than the next higher value. It holds true for anything above 7. A PH level of 9 is ten times more basic (alkaline) than a PH scale of 8. Therefore a PH level of 0 is super acidic and a PH level of 14 is strongly basic. Some examples of acidic substances is vinegar and lemon juice. In addition battery acid would be a 0 on the scale. Water is neutral and Lye and ammonia are examples of basic substances. Liquid drain cleaner would be a 14 on the scale. This is to just kind of give you an idea of what is highly acidic and what’s highly basic. The PH scale is all intertwined with acids and bases. Here is a chart to show you a little of what I mean.
