WebThe pH scale ranges from 0 to 14, with a pH of 7 indicating neutrality, values less than 7 indicating acidity, and values greater than 7 indicating basicity. The pH scale is based on the hydrogen ion concentration, with each pH value representing a tenfold difference in hydrogen ion concentration. p [H] [ edit] WebWhat is pH? pH is a measure of how basic or acidic a substance is. pH has a range of 0-14.
