« on: March 06, 2008, 04:47:52 AM »
Which acid should be stored in plastic containers rather then in glass ones??
a) hydroflouric acid
b) nitric acid
c) phosphoric acid
d) sulfuric acid

How do u approach this problem?? Or is it one of the things that we have to memorize??

Do you know chemical properties of these acids? What do they react with?

Yes, pretty much, as you can see from the responses below.

You can try and figure it out, if you look on the lab shelf.  There may be glass bottles of all but one of those acids.  But nowadays, resistant plastic is cheaper to ship, so that trick may not even work for you.  Have you used any (most? all but one?) in lab experiments, using standard glassware?  Failing that, just look each one up in your text book's index, one of them is very interesting, the others pretty typical.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
