In a solution of pH5, the concentration of hydroxide ions will be [tex]10^{5}[/tex] M.
Chemical reactions in a medium are influenced by the concentrations of protons in the medium. The hydrogen potential or pH of an aqueous solution tells us about the molar concentration of dissociated H+ by applying the negative logarithm.
Knowing then the pH of a solution we can calculate the hydrogen concentration of the given solution as follows:
[H+] = [tex]10^{pH}[/tex]
Also inversely we can know the pH knowing the concentration of hydrogen in a solution:
pH = -log [H+]
Therefore, we can confirm that in a solution of pH5, the concentration of hydroxide ions will be [tex]10^{5}[/tex] M.
