The hydroxide ion concentration in a solution is 3.31*10^-8M.

To find the answer, we have to know more concentration of solution.

How to find the hydroxide ion concentration in a solution?

  • It is given that, the pH is 6.52 at 25 degree Celsius.
  • We have the expression for pH in terms of hydronium ion concentration as,

                     [tex]pH=-log[H_3O^+][/tex]

  • Thus, the hydronium ion concentration is,

                   [tex][H_3O^+]=-10^{pH}=10^{-6.25}=5.6*10^{-7}M[/tex]

  • We have to find the concentration of hydroxide ion, for this we have an expression,

                        [tex]K_w=[H_3O^+][OH^-]\\Where,\\K_w=10^{-14}[/tex]

  • Thus, the hydroxide ion concentration in a solution is,

                         [tex][OH^-]=\frac{K_w}{[H_3O^+]} =\frac{10^{-14}}{10^{-6.52}}\\\\[/tex]

                           [tex][OH^-]=3.31*10^{-8}M[/tex]

Thus, we can conclude that, the hydroxide ion concentration in a solution is 3.31*10^-8M.
