I don't like the idea of using KOH, mostly because it's hard to tell what I'm getting when I weigh it because it turns into a puddle while I weigh it.
You can titrate it with a standard acid. You can make a standard acid by titrating that with a standardized base. Or, you can use potassium acid phthalate (KHP, or potassium hudrogen phthalate) which is a common standard acid and titrate the KOH solution directly with the KHP solid. Use phenolphthalein as the indicator.
That's what all the hip lab cats do, man.
For up from the ashes, up from the ashes, grow the roses of success!
