Bernd, thanks for spotting that. Yes, looks like you’re right. I should’ve spotted that. Getting my bisulfites mixed up with my hydrogensulfates (bisulfates). Fixed now.

Nice piece of art
and I don’t want to spoil the fun, but:
isn’t sodium hydrogensulfate (NaHSO4) rather useless for “neutralising” hypochlorite?
Perhaps it should read sodium bisulfite (NaHSO3) or disulfite (Na2S2O5) instead. Sodium thiosulfate does the job as well.

Yeah, I realise that Adam ;-) It’s usually something less well known or more complex, like a protein, that one expects not to crystallise, right? I was very surprised to learn there was no crystal structure for sodium hypochlorite.

Just because something has the ability to solidify does not mean a nice single crystal can be grown for proper x-ray analysis. Ask many an organic chemist trying to coax that one, nice, single crystal. It can actually be quite challenging. And if the compound is the least bit hygroscopic... There are many resources for trying to grow good single crystals
