pH =12 is a very strong base.
The high value pH is #14#.
If you are using the common English definitions of "strong" (meaning 'more') and "weak" (meaning 'less'), then a strong base will have a pH of 12-14 while a weak base will have a pH of 7-9. However, there is a specific scientific definition of 'strong' and 'weak' when used to describe acids and bases. In chemistry, a 'strong base' is a base that completely ionizes in water while a 'weak base' is a base that partially ionizes in water. If you are using these definitions, there is no way to categorically compare the pH of a strong base versus the pH of a weak base - the two variables do not related. Some strong (complete ionization) bases will have a lower pH (7-9) while other strong (complete ionization) bases will have a higher pH (12-14); the same is true of weak (partial ionization) bases.
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.
pH levels indicate the acidity or alkalinity of a substance on a scale from 0 to 14. A lower pH (0-6) indicates acidity, while a higher pH (8-14) indicates alkalinity. pH 7 is neutral. The acid-base spectrum ranges from strong acids (pH 0-2) to weak acids (pH 3-6), neutral (pH 7), weak bases (pH 8-11), and strong bases (pH 12-14). pH levels and the acid-base spectrum are directly related, with pH values determining where a substance falls on the spectrum.
A very strong base would have a pH of 12, 13, or 14
A pH value greater than 10 represents a strong base. Strong bases have a high concentration of hydroxide ions and can be corrosive.

It's a base not an acid usually containing the hypochlorite ion. The pH is usually about 12.

pH levels indicate the acidity or alkalinity of a substance on a scale from 0 to 14. A lower pH (0-6) indicates acidity, while a higher pH (8-14) indicates alkalinity. pH 7 is neutral. The acid-base spectrum ranges from strong acids (pH 0-2) to weak acids (pH 3-6), neutral (pH 7), weak bases (pH 8-11), and strong bases (pH 12-14). pH levels and the acid-base spectrum are directly related, with pH values determining where a substance falls on the spectrum.
No. Alkali's and acids are an separate ends of the pH scale, the pH of acids being 1, 2, 3, 4 and 5 (strong to weak) and the pH of alkali's being 11, 12, 13, 14 and 15 (weak to strong). Examples of acids are hydrochloric acid (strong) and vinegar (weak). Toothpaste is an example of a weak alkali.
A pH value greater than 10 represents a strong base. Strong bases have a high concentration of hydroxide ions and can be corrosive.
A very strong base would have a pH of 12, 13, or 14
The pH of a weak base can be anything greater than 7.0. Generally, weak bases do have a lower pH that strong bases, but this is not always true. The fact that a base is weak only means that it does not completely ionize in solution. The pH of a weak base depends only upon the concentration of hydroxide ions (OH-) in solution.
A strong base would have a pH value ranging from 10 to 14. Examples of strong bases include sodium hydroxide (pH 12-14) and potassium hydroxide (pH 12-14).
No, pH 12 indicates a strong base, not a strong acid. A strong acid would have a pH value below 7.
To buffer a solution with a pH of 12, you would need to add a weak acid and its conjugate base in appropriate amounts. This will help prevent drastic changes in pH when an acid or base is added to the solution. Common buffer systems for a pH of 12 could involve using a weak base like ammonia (NH3) and its conjugate acid ammonium chloride (NH4Cl).
