I bought a bottle of silver testing acid off eBay. The bottle tipped over, I found it the next day, and the top fell off. This is the 3rd time this has happened. I thought acid won't eat plastic?
Yup, depends on the acid and the plastic. Just like hydrofluoric acid will eat about anything but teflon, chlorosulfonated polyethylene and natural rubbers are resistant to it.
It wasn't caused by the acid, it was caused by either a defective top or over-tightening by the user. Notice these bottle have a conical plastic dropper and if they are overtightened, the pressure is on the center which causes it to break at the weakest part, the right angle between the top and side. Blame the thin cheap plastic top ( probably PVC). IMO. See this a lot in beginning chem and microbiology labs. Everyone is warned about certain reagents and overcompensates.
Guess you'll have to ask what the proper way to put a 'silver testing acid' bottle down so it won't tip over (I'm sure that's what is in that bottle...how's the AT going?), as you ask how everything else needs to be done.....but after 3 times, I think it's a bit late for you to learn....... How do you keep cans from falling over????
