what is pH scale?
;))bye final wala
Answers
Explanation:
In chemistry, pH is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions. The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution.

• Formula
FormulaTo calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].

• Symbol
The 'H' in pH is the elemental symbol for hydrogen. The 'p' can refer to different things in different languages, but the 'pH' is most commonly said to mean 'power of hydrogen'. So what does this mean? The hydrogen referred to in the pH symbol is actually the hydrogen ion, which is written as H+.

• Basics
BasicsThe pH scale
BasicsThe pH scaleAnything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. pH scale, ranging from 0 (very acidic) to 14 (very basic/alkaline) and listing the pH values of common substances.
