Default Sodium sulfite precipitate

Nothing earthshaking, just interesting.

I keep a bottle of sodium sulfite concentrate that I use for hypo
clearing agent. Checked the bottle yesterday and was surprised to find
big chunks in the bottom. *Really* big chunks. I guess they're big
Na2SO3 crystals. They're clear, like ice, not like salt. They're hard.
One was so big I had to shake and break it to get it out of the bottle.
Weird.

They all redissolved easily after heating in a pan on the stove.
