pHtasojen
pHtasojen refers to the levels of acidity or basicity of a solution, quantified on the pH scale. The pH scale runs from 0 to 14 at standard room temperature, with 7 considered neutral. Values below 7 indicate acidity, values above 7 indicate basicity (alkalinity). The pH value is calculated as pH = -log10[H+], where [H+] is the activity of hydrogen ions in moles per liter. Because it is a logarithmic scale, each unit change corresponds to a tenfold change in hydrogen ion concentration.
Measuring pH can be done with pH meters, which use a glass electrode to sense hydrogen ion
pH plays a central role in chemistry, biology, medicine, agriculture, and environmental science. In living organisms,
Care is needed when interpreting pH in non-aqueous solutions or at extreme temperatures, because the standard
