... ratio is ( mmoles salt / ml ) / ( mmoles acid / ml ) , and the volumes cancel . So we can take the ratio of ( mmoles salt ) / ( mmoles acid ) : mmolesHOAC = 0.10 X 10 = 1.0 mmolesoAc = 0.10 X 20 = 2.0 2.0 pH = 4.76 + log = 5.06 . 1.0 ...

... ratio of [ Redin ] / OXIn ] . This is analogous to the ratio of the different forms of a pH indicator being determined by the pH of the solution . So the ratio , and therefore the color , will change as the potential of the solution ...
