When you use the powdered pottasium hydroxide do you mix up a liter or so and keep handy for future feeds or mix as needed?
I've only really used it for the Beam's test sol'n. Bought a bottle of EverClear and took out 250ml for sipping on and added some KOH to the remaining 500ml. Only need a few drops for each test so should last me forever. If I were going to make pH up with it I'd pre-mix a liter or more so it's ready to go. It's very exothermic so if using a plastic bottle make sure you add it to lots of water. It'll get warm but not so warm it will melt the plastic. Pop bottle or clean milk jug would be fine. Do not use an aluminum container as it will react with Al.
