>Bill - are you saying you are suprised that a 3% solution of potassium hydroxide has a pH of 14? If so, here's the way to calculate it.
No, what I mean is that I recall having seen in the past Rodinal packaging which maintained that the pH of the solution was a few units lower, which would indicate a substantially different formula from anything being discussed here. I remember pH 9.8 or something like that ? ? ? It's just something that stuck in my head and could easily be wrong.
