I think it would be fair to insert the word "formal".
You mean you don;'t have a bench supply???
Well, I have some orphaned in-line or wall-wart supplies intended for
computers, radios, etc. that I could chop the connectors off of. But
I figured the jump cables could put out more current.
H2 normally comes off at the -ve electorde too...
Yes, and I do know which jump cable is negative. So I guess I
shouldn't claim I was "lucky". But I was pretty prepared to be wrong,
on the whole. Chemistry puzzles me.
It's not uncommon to get Cl2 at the positive
electrode. Another reason to
do it in a well-ventilated area.
True! I forgot about that. The chemistry book we were looking at said
at a more concentrated solution of salt was more likely to produce
Cl2. That was a pretty simple mnemonic for me to remember, so I
didn't use much salt.
