I want to know if it is okay to mix used sodium thiosulfate with used acidic ammonium thiosulfate while awaiting disposal. It is a chemistry question: will I produce sulfur dioxide or is it fine?

Sorry... didn't mean to touch off a firestorm of disposal opinions.. I actually thought it was a simple question! I'll try to ignore the stereotyping based on where I live. Wow.

Indeed, let's keep the politics out of it, and if anyone can answer the question to keep the thread on topic, that would be appreciated.
