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...
A good pH balance significantly affects your overall health, which doctors and scientists agree upon. Your body's pH, or potential hydrogen level, is influenced by the food and drinks you consume. pH is the measurement of hydrogen ion concentration. This measurement is based on a scale that ...

pH is a measure of how acidic or basic an aqueous solution is. It is calculated as the negative logarithm of hydrogen ion concentration. pH Definition and Origin pH is the negative log of hydrogen ion concentration in a water-based solution. The term "pH" was first described by Danish bio...
A glass electrode and pH metre, or colour-changing indicator, may be used to measure the pH of aqueous solutions. pH of Acids and Bases – Red Litmus Test pH Abbreviation pH may be seen as an abbreviation of the power of hydrogen-or, more fully, the concentration of hydrogen ion in a...
, where frequent water exchange occurs. Despite this fact, the organisms that depend on rivers require some equilibrium. Various indicators give a measure of the quality of a river. These measurement include dissolved oxygen, temperature, and pH, which is a measure of hydrogen ion concentration....
pH is a measure of the hydrogen ion activity, typically in aqueous solution. In pH, the p stands for -log10 and the H stands for hydrogen ion activity: pH = -log10aH+ In dilute solutions, the activity of hydrogen ions can be approximated by their molar concentration, and it is in...
The pH of a solution is a measure of the hydrogen (or hydronium) ion concentration and is defined as {eq}pH\:=\:-log\:\left[H^+\right] {/eq}. Below pH 7, solutions are considered acidic. Above pH 7, they are considered basic. At pH 7, they ...
What is the pH if the hydrogen-ion concentration is 6.8×10−7 M? pH: The pH scale is a dimensionless logarithmic scale that allows one to determine whether a solution is acidic or basic. Basically, the pH scales ranges between 0 and 14. Any pH value that falls within 0−7 descr...
