What is the pH Scale? - ReAgent Chemical Services The pH scale is a precise way of classifying the acidity, basicity or neutrality of a solution. As a logarithmic scale, 1 pH unit is ten times stronger, or ten times weaker, than the one below or above it, depending on its position: a pH of 4 is ten times more acidic than a pH of 5, but ten times weaker than a pH of 3. The pH scale - Acids, bases and salts - (CCEA) - BBC Bitesize The range for the pH scale is 0 (strong acid) to 14 (strong alkali). pH 0 - 2: strong acid. pH 3 - 6: weak acid. pH 7: neutral. pH 8 - 11: weak alkali. pH 12 - 14: strong alkali.

Below mentioned are some key features of the pH scale that one must know.

The pH Scale - Chemistry LibreTexts The Effective Range of the pH Scale. It is common that the pH scale is argued to range from 0-14 or perhaps 1-14, but neither is correct. The pH range does not have an upper nor lower bound, since as defined above, the pH is an indication of concentration of H +. For example, at a pH of zero the hydronium ion concentration is one molar, while at pH 14 the hydroxide ion concentration is one molar.

4.16: The pH and pOH Scales - Chemistry LibreTexts Knowing the dependence of $pH$ on $[H^+]$, we can summarize as follows: If pH < 7.00, then the solution is acidic. If pH = 7.00, then the solution is neutral. If pH > 7.00, then the solution is basic. This is known as the $pH$ scale. The pH scale is the range of value s from 0 to 14 that describes the acidity or basicity of a solution. You can use $pH$ to make a quick determination whether a given aqueous solution is acidic, basic, or neutral.
