Which pH value represents a solution with the lowest OHM<br> ion concentration?
Arlecino [84]

pH value 1 represents a solution with the lowest OH⁻ion concentration.

<u>Explanation:</u>

pH is given by the expression as the negative logarithm to the base 10 of the concentration of hydrogen ions.

pH = -log₁₀[H⁺]

If the pH is lower than 7, pH < 7 then it is acidic

If the pH = 7, then it is neutral

If the pH > 7, then it is basic

If pH is 1 then the solution is showing mostly acidic character,which is least basic in its character.

So if the pH is 1, which is most acidic and least basic solution that is lowest OH⁻ ion concentration.
