c)magnesium sulfate
d)10% NaOH
e)sodium hypochlorite

for
d)10% NaOH would it be aqeous?

I'm now thinking that
for methylene chloride and sodium hypochlorite they would go in halogenated organic waste bottle b/c they have Cl but this may be wrong...

Somewhere in your course you will be given, or should be given, oral instructions or written instructions about the disposal of different types of chemicals. The reason is that pouring any unused material down the drain is no longer accreptable. So there are disposal jars/buckets/barrels/crocks/etc labeled and the instructions are to help you know which crock in which to throw your trash. Most of the decisons made concerning what goes in a certain disposal jar are dictated by the companies that pick up these items for disposal.
From the description you have given, I would go with the following.
hexane is a non-halogenated organic.
methylene chloride is a halogenated organic.
The next three are water soluble; therefore, I would place all of them in the aqueous jar (although the question isn't clear as to MgSO4 solution or MgSO4 solid). There COULD be problems with placing a strong oxidizing agent and a strong reducing agent in the same aq jar but in the absence of other information that is where I would place the NaOCl.

This question was posed in my post lab questions as I'm supposed to look this info up.
They expect us to find out all this on our own.

Thanks Dr.Bob =D
