* pH Scale: The pH scale ranges from 0 to 14.
* 0-6.9: Acidic solutions (higher hydrogen ion concentration [H+])
* 7: Neutral (equal concentration of hydrogen and hydroxide ions)
* 7.1-14: Alkaline or basic solutions (higher hydroxide ion concentration [OH-])
What pH actually measures:
pH is a measure of the hydrogen ion concentration ([H+]) in a solution. The more hydrogen ions present, the more acidic the solution.
The equation for pH is:
pH = -log[H+]
* log: This is the logarithm function, which helps to express the wide range of possible hydrogen ion concentrations in a manageable way.
* [H+]: This represents the concentration of hydrogen ions in moles per liter (M).
In simpler terms:
Think of pH as a way to describe how "sour" or "bitter" a solution is. A low pH means the solution is very acidic (sour), while a high pH means it is very alkaline (bitter).
