CO2 to prevent oxidation?

Greetings,

Could I preserve my chemicals by using a protective "blanket" of carbon dioxide gas? I have tons of it from my old beer brewing days.

Cheers! Ken

The usual answer is nitrogen or argon. CO2 might work, or might react and change the composition a bit. I'd be wary because bubbling CO2 through solutions is a way to change carbonates to bicarbonates (so I'm told).

Kenneth, CO2 dissolves in water to make carbonic acid (H2CO3). It's like seltzer water and it's acidic. It will react with (neutralize) the alkaline component (accelerator) in developers. I wouldn't recommend using CO2.
