What pH Levels Are Considered Strong & Weak? ... However, because pH measures the amount of hydrogen ions released in a solution, even a very strong acid can have a high pH reading if its concentration is very dilute. For instance, a 0.0000001 molar HCl solution has a pH of 6.79. As a strong acid, HCl exhibits 100 percent dissociation, but the ...

the pH scale goes from 0-14, 0 being most acidic, and 14 being least acidic, or basic. 7 is neutral. water has a pH of 7. So a very strong acid would have a pH of in the range of 0-2.

A strong acid is an acid where the pH is lower than, generally, 3. These acids are in very high concentration of H+ ions (an acid of pH 3 has 0.001 moles per liter of H+), while a weak acid’s pH ...

en.wikipedia.org/wiki/PH

A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm −3 has a pH of 0. A solution of a strong alkali, such as sodium hydroxide, at concentration 1 mol dm −3, has a pH of 14. Thus, measured pH values will lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.

A strong acid is one which completely dissociates into its ions in water. This makes calculating the hydrogen ion concentration, which is the basis of pH, easier than for weak acids. Here's an example of how to determine pH of a strong acid.

How to Calculate the PH of a Strong Acid ... (H+) in water solutions. pH is the logarithm scale that quantifies the solution acidity level; pH = - log [H+] where [H+] represents the concentration of hydrogen ions The neutral solution has a pH of 7. Acidic solutions have pH values below 7, while a pH greater than 7 is basic. ...

They are medium-strong bases. Anything with a pH level over 7 is a base, 8 being a weak base and 12 being a strong base. Anything Below 7 is an acid, 6 being a weak acid and 0 being a strong acid.

Example: Working out the pH of a strong acid. Suppose you had to work out the pH of 0.1 mol dm-3 hydrochloric acid. All you have to do is work out the concentration of the hydrogen ions in the solution, and then use your calculator to convert it to a pH. With strong acids this is easy. Hydrochloric acid is a strong acid - virtually 100% ionized.

In technical words, the acid which dissociates completely into H+ ions in water will have the lowest pH value, while the base dissociates completely into OH- ions in water will have the highest pH value. EDIT : Strongest acid has pH of 1 while strongest base has pH of 14. (0 - 6.99 are acids. 7 is neutral. 7.1 - 14 are bases.)
