The bottle labeled “ammonium hydroxide” in my chemical cabinet at work/school is much stronger than the stuff used for diluting and cleaning at home. I’ve poured it in an open exterior doorway for kids and still had them complaining as they held their beakers at arm’s length.
Oh, someone mentioned glacial acetic acid (pure vinegar to the rest of you, not that 5% stuff you get at the grocery). I didn’t seat my reflux tube correctly in my apparatus setup in organic chem lab, and the fumes were so strong through the lab (I was heating this strongly) that everyone walked out until I fixed it, then stayed a few minutes longer with the doors open to the outside. Ick.
I don’t want to start a new thread about it, but if anyone knows, is there a time when one would use ethanoic acid over acetic acid as far as word usage goes? Is one more common?
