I've been doing some reading on Chloroform and how you make it. I found hth spa shock at my local hardware store which has a decent % of Calcium
Hypochlorite but has a lot of other stuff in it. I was just wondering if it's still good to use for this reaction considering the other things in it.
I tried doing some searching on this site but didn't find much (Unless I over looked something)
Anyway, thanks a lot for answering my noob question in advance!

I tried it. The RXN went beautifully, but the precipitate of calcium hydroxide mixed in with the chloroform and I couldn't reasonably separate the
two.
Next time I try it, I'll first add NaOH to exchange with the Ca and filter off the precipitate before the haloform RXN. Granted NaOCl is limited to
about 23% solution, but the hydroxide side product has excellent aqueous solubility.

Yes, the reaction generates Ca(OH)2 which doesn't dissolve in water and you get a thick slush. The solution is simple : distill the chloroform out of
the solution.
