Storage of Conc HCl
Posted: 26 Mar 2018, 14:27
Hi All,
Had a bit of a fright today. Was about to make up some dilute HCl but when I opened the bottle of concentrated HCl all this gas started erupting from under the lid as soon as I slightly twisted it (as in the lid was still basically on and not screwed all the way off). I fully admit I squeaked and jumped back, and was extradinarily grateful that I was wearing full PPE and doing it in the fume hood, but it was still super scary and there is a gap between my gloves and my lab coat sleeve, and my face isn't covered beyond my safety glasses... I eventually took the whole lid off and it continued to steam scarily so I've left it alone in the fumecupboard.
Anyone know why my bottle of concentrated HCl did this and how to prevent it?
