I know I am appearing dumb. Can someone help me with solution equlibria in GC?.. I want to know how do we relate the concentration of the two ions of a solute in a solution? In Kaplan it says
[OH]- = 3[Fe]3+... I do not understand.

Thank u

Fe(OH)3 ---> Fe3+ + 3 (OH)-


So for dissociation of every mole of Iron (III) hydroxide, one mole of Fe3+, and 3 moles of OH- ions are formed. Therefore [Fe3+] = 3[OH-].
