does SN oxidize?

[gothfairy]

my SN came today. i opened it. will it oxidize and be ruined?

IIRC It doesn't but don't take my word for it, your response lies in the SN megathread, I know someone responded to that...

NO.
Unless you're in a sauna you can open and close it several times :)

SN very durable even in a water solution .

Solid – not very reactive (slowly oxidize over long time). Clamps fine. Air-tight container can be opened and closed, won't go bad.
Solution (strong) – labs store it at room temp, open & close, a bit of oxygen is fine. Homemade solutions are not purified water, so should not be stored, but potency is maintained for at least several hours..

More data sheets & temperature -

finally found data sheet for 40% solutions , like ours :

[addendum]

• Someone wrote here, in this thread, that SN is hygroscopic, absorbs moisture, "reacts" with water – true! – like regular table salt .
• "React" : SN dissolves to suspended ions , which is not a reaction . In a reaction chemicals actually bond to produce new substance . SN does not break water molecules to bond with hydrogen or oxygen , thus not reactive ..
