Sodium metabisulfite? More like sodium 'meta-busy-sulfite' if you ask me. I bet the chemists had a field day coming up with that one!

An emulsifier? Did someone spike the parenteral formulation with a little too much party mix?

A cosolvent? That's a new one. I think I'll stick with the good old antioxidant option.

A solubilizer? Nah, that doesn't sound right. This is more of a stabilizing agent, isn't it?

Hmm, I'm not sure about that. Isn't a chelator something that binds to metal ions? Seems like a stretch for this question.

Definitely an antioxidant! Sodium metabisulfite is a common preservative used to prevent oxidation in parenteral formulations.

I'm not sure about that, I think it could also be used as a chelator to bind metal ions.
