I have several lbs of Sodium Chlorite (flakes), which I would like to use to generate Chlorine Dioxide gas in order to remove odors from rooms, autos, boats, etc.

There are commercial products sold for the same intended purpose. Looking at the MSDS for one such product (not sure if I'm allowed to post links?), it appears to be a packet of powder consisting of Sodium Chlorite 30%(by weight) , and "Inorganic Acid" 70%(by weight). Water is then added to the powders in the packet, in order to produce Chlorine Dioxide gas. One 10gr packet apparently produces enough gas to deodorize and disinfect up to 250 sq feet.

So my question is, does the type of acid I use matter a great deal? And if so, is it all just a question of efficiency? Certain types of acid produce more gas from same amount of Sodium Chlorite?

Not sure which "inorganic acid" that the commercial "Odor bombs" use?

I have powdered Citric and Acetic acid on hand already. I'm sure I have phosporic and muriatic out in the garage somewhere.

I've also read somewhere that Hydrogen Peroxide can be added to Sodium Chlorite when working on small scales, but I don't have any idea what % solution or amount.

My first inclination would be to just "go for it" and use the same 70/30 ratio that the commercial products use, but having forgotten nearly every single thing I learned yrs ago in HS Chemistry, figured I better check in with the experts to learn what I can.

My proposed course of action:

Mix 3gr Sodium Chlorite 7gr Citric Acid

Add 12ml water

close windows/doors

Am I on the right track?

Any suggestions?
