Is that purity possible in NH4OH? I'd been under the impression that anything
near that concentration would decompose into ammonia and water, and that
amount of that ammonia would exit promptly.

Here's a good test; it should smell overwhelmingly of ammonia when you
container. I was a little surprised in your earlier description that you
mention using such stuff outdoors or under a lab hood. It would seem dangerous
to have such stuff open and indoors. (I've got a jug of 28% NH4OH that I'm
terrified of opening -or dropping!!- indoors.)
Another test is that it should leave essentially no residue when it
Could the marking on the label possibly mean that it contains 98.8% deionized
water? I've seen the terms DI or DI water used a lot for that in various
