Logarithmically.
By powers of ten.
pH 1 is 1000 times more acidic than pH 3. 10 * 10 * 10, or 103
Acids have pH values below 7.0. Bases have values above 7.0.
14
Danze16
The range of pH values is 0 - 14.
Bases are repestented by values greater than 7 on the pH scale.
pH values are indications of acidity/alkalinity of a solution.
Nothing. pH values indicate acidity levels.
pH values higher than 7.3
A box of pH paper has printed the colors and the pH values.
Some buffer solutions maintain pH at 7, but others have different pH values. It is common to have buffers with pH values of 4, 7, and 10 for calibrating pH meters, for example.
Because water is a neutral and high pH values are basic and low pH values are asidic.
Its colour changes over a range of Ph values.
