The representation of concentration of H+ ions and OH- ions is represented by the ph scale .
When the number of H+ ions equals the number of OH- ions, the water is neutral. It will than have a pH of about 7. The pH of water can vary between 0 and 14.
0 being most acidic and 14 being most basic .
Explanation:
pH means "puissance d'hydrogène" or "strength of hydrogen".
The definition is pH = -log₁₀[H⁺].
