Many years ago I bought a bunch of Sodium Chlorite, put it in a cupboard and forgot about it.  This week I needed to make and use some Chlorine Dioxide, and when I opened the cupboard all the Sodium Chloride had seeped through the plastic and evaporated leaving piles of white salt in the cupboard.

Can I mix the salt with more water to reconstitute it?  Is the while salt NaClO2?  Or just NaCl?  How do I tell?

Edit - second time I am trying to post this, the first time it just disappeared when I pressed submit.

Many years ago I bought a bunch of Sodium Chlorite, put it in a cupboard and forgot about it.  This week I needed to make and use some Chlorine Dioxide, and when I opened the cupboard all the Sodium Chloride had seeped through the plastic and evaporated leaving piles of white salt in the cupboard. I had a similar experience a few years ago. The Sodium Chlorite dissolved the plastic bag and created thousands of tiny pieces of plastic.

I found that when I was making sodium chlorite solution from the sodium chlorite, that most of the tiny pieces of plastic floated to the surface, which I then removed.

Now, I store sodium chlorite in glass bottles with plastic lids. I will be adding PTFE (teflon) discs to the underside of the bottle caps. Teflon is chemically inert. 


Can I mix the salt with more water to reconstitute it?  Is the while salt NaClO2?  Or just NaCl?  How do I tell? I would think that the salt is NaCLO2.
