http://chemistry.elmhurst.edu/vchembook/184ph.html WebbpH = −log ([H +]) The formula for pH is shown above. pH is defined as the negative log base 10 of the hydronium concentration. The pH is a logarithmic measure of the concentration of hydrogen ions in a solution. Because pH is on a log scale that means that increasing the pH by 1 corresponds to multiplying the concentration of H + ions by 10

WebbThe pH of a substance is a measure of how acidic or basic the substance is. Measured on a scale from 0 to 14, pH is based on the concentration of hydrogen ions in a solution. In pure water, which is neutral (neither acidic nor basic), the concentration of hydrogen ions corresponds to a pH of 7.0. This marks the midpoint of the pH scale.
