Question

details about ph scale chemistry

Answer 1

Well, p stands for potenz which means power and H stands for Hydrogen, it basically functions on the basis of concentration of H+ ions of a substance, it was introduced by Søren Peder Lauritz Sørensen at , it has a scale of around 0 - 14 , 0-7 indicates acidic content, on the other hand 8-14 indicates basic content, while 7 is neutral.

Hope it helped.
Regards. :D

Answer 2

A measure of the degree of the acidity or the alkalinity of a solution as measured on a scale (pH scale) of 0 to 14. The midpoint of 7.0 on the pH scale represents neutrality, i.e., a "neutral" solution is neither acid nor alkaline. Numbers below 7.0 indicate acidity; numbers greater than 7.0 indicate alkalinity. It is important to understand that pH is a measure of intensity, and not capacity; i.e., pH indicates the intensity of alkalinity in the same way temperature tells how hot something is, but not how much heat the substance carries.

The pH scale is logarithmic which means that moving on (unit either way on the pH scale results in a 10 fold increase in the degree of alkalinity or acidity.
