Hi ,

Dilly, yeah I mix 4 litres in a 10 Litre carbaloy container. I mix in about half then the other half. Only because the scales are too much of a pain to measure 200 grams of KOH. There is about as much pressure as say a cooke bottle being opened. I dont particularly think its dangerous but I would consider mixing 20 litres in something larger than a 25 litre container. Maybe mix up to 10 litre batches. Incidently I'm sure you meant 1.4 times and not 1.4%. (huge difference)

Geewiz good point about the purity of the reactant. If your using the same reactant for titration as for mixing then as you say, it sorts itself out. I think this whole business of conversion has really been confusing people for a while now.

Keep up the questions and keep us posted on how you are going.
