What exactly is pH?

pH is commonly known as the measurement of how basic or acidic a solution is. The “p” stands for power, or potential, and the “H” stands for the element of hydrogen. The greater the potential a solution has for freeing hydrogen ions, the lower the pH will be.  

Generally solutions that have a pH of less than 7.0 are said to be acidic, while those more than 7 are basic, or alkaline. For example, water, which is neutral, has a pH of 7.0.

The pH scale is logarithmic, which means that each whole pH value below 7 is ten times more acidic than the next higher value.

                        These are the pH measurements of common solutions.
