pH is a unit of measure which describes the degree of acidity or alkalinity of a solution. It is measured on a scale of 0 to 14.
To determine the pH of water, a pH meter can be used to measure this important water quality parameter.
The term "pH" is a measure ofhydrogenionconcentration, a quantitative measure of theacidityoralkalinityof asolution. In chemistry, the pH scale usually ranges from 0 to 14.Aqueous solutionsat 25°C with a pH of less than 7 areacidic, while those with a pH greater than 7 are basic oralk...
Exam-OTE H +, rather OTE Where a pH measure- give rise to errors of approximately 1 pH unit, and the hydrogen-ion response of the glass electrode are all changed. For these reasons, the values so obtained with solutions 12、that are only partially aqueous in character can be regarded ...
