More on the electrolysis of salt water

It looks like a secondary reaction -- involving the salt and the water -- and possibly a second secondary reaction involving the copper, explains a lot of what we saw in our version of splitting water molecules.

A concise explanation can be found on a discussion board at a British site called The Naked Scientists. Explains everything except the black flakes. Have to keep working on that bit.

use graphite instead of copper and the black flakes will be gone
