Default De-ionizing water

There is not one particular experiment, but you can be assured it isn't
anything which might be hazzardous. I want to learn Chemistry, but I don't
have the time or money to take courses at a university. As I am a graduate
student in math. Besides, isn't it very difficult to even get your hands on
any "fun" elements/compounds, etc...? That is to say, obtaining anything
which might be considered potential "terrorist" materials is much more
difficult.

Just buy a Brita filter - it contains ion exchange resins and some charcoal

There was a thread a while back on what chemicals are available
reasonably pure and under what names, with the results listed on a
website somewhere. Someone might remember the site, maybe.

I have trouble believing this. The grocery store DI water that I've
used in the past did not contain significant ionic impurities, as
gauged by both chemical tests and resistance. Perhaps it depends on
the brand. Personally, I would call labelling softened water as
"deionized" unethical or downright fraudulent.

Of course, you're correct about the problem of ionic leakage as the
bed nears exhaustion, but that's something the vendor should be aware
of, and guard against.

AAhhh!!! I see. Well, I'll look into that. I just hope that I can find a
Chem. prof. who'll let me.

How does this audit credit work ??? Something different from my college days
.... of course electricity is also used now for lights ...
We would sit in classes all the time ... sometimes for just one topic ...
sometimes for the semester ... Never got or looked for credit ... just the
knowledge ....

I don't know that there are any industry standards covering water you buy at
the grocery store. If not, maybe there should be.

Op Cit, water in California.
The water tastes like crap going into a Brita filter, indistinguishably
better coming out.

In my day (long ago), some places would list it on your record that
you audited for no credit. Maybe not now.
