Question

Highest concentration of $O{H}^{-}$ ions is present in the solution with which of the following pH?

• A. $1$
• B. $6$
• C. $11$
• D. $12$
• E. $14$

Answer 1

The correct option is E $14$

Highest concentration of $O{H}^{-}$ ions is present in the solution with pH 14.
Higher is the hydroxide ion concentration, lower is the hydrogen ion concentration and higher is the pH of the solution.
