In chemistry, pH is a dimension of the awareness of hydrogen ions in a water-based solution. A lower pH potential that there are extra hydrogen ions in the liquid, whereas a higher pH indicates fewer hydrogen ions in the liquid.
For example, concentrated hydrochloric acid can have a pH of round -1, whilst sodium hydroxide solution can have a pH as high as 15.
Lower pH variety skill greater acid, higher pH quantity capability enhanced base. It can be a little confusing, however the lower the pH of a substance is, the more advantageous of an acid it is.
