It is used every day in countless … Webb10 mars 2024 · In chemistry, the pH scale is a common application of a log scale. The pH scale measures the concentration of hydrogen ions in an acidic or alkaline substance using the equation: 10 - pH = H+. This logarithmic formula shows how acidity increases by factors of 10 for each unit by which the pH decreases. As this scale uses powers of 10, a …

This value is … Webb2 mars 2024 · The pH scale is used to indicate how acidic or basic a solution is. It ranges from 0 to 14, where 7 is neutral. Anything less than 7 is classified as acid and anything above 7 is classified as a base.
WebbThe pH scale was developed by Danish chemist S ø ren Peter Lauritz S ø rensen (1868 – 1939) in 1909 and is generally presented as ranging from 0 to 14, although there are no theoretical limits on the range of the scale (there are substances with negative pH's and with pH's greater than 14, although for most substances the range of 0 – 14 suffices).
