Depends on the pH, at low pH (below pH 7), the H+ ion concentration is greater, and high pH the OH- ion concentration is greater
The higher the pH, the greater the concentration of Hydroxide (OH-) ions. So, the solution with the pH of 9 is your answer.
the H+ concentration and the OH- concentration
pH = - log([H+]) , pOH = - log([OH-] , pH + pOH = 14 [X] = concentration of X
pH 2
The concentration of H+ or OH-.

the concentration of OH ions in solutions
pH = - log([H+]) , pOH = - log([OH-] , pH + pOH = 14 [X] = concentration of X
An increase in the concentration of OH- ions.
Adding a base will make the pH go up (increasing of OH- ions concentration).
pH=10, means the concentration of OH- ions is 0.0001 M and concentration of H+ ions is 0.0000000001M
pH 2
pH
The difference between the three is the relative concentration of H3O+ and OH- in the solution.An acid solution has a higher concentration of H3O+ than OH- and its pH is lower than 7.A basic solution has a higher concentration of OH- than H3O+ and its pH is higher than 7.A neutral solution has exactly equal concentration of each one and its pH is exactly 7.
