Just a heads up, it’s definitely not an emulsifier.

Wait, are we sure it’s not a chelator? Sounds fishy.

I’m a bit confused. I thought it could also act as a chelator, but now I’m leaning towards antioxidant.

I recall a practice question about antioxidants in parenteral formulations, and sodium metabisulphite was listed there too. It seems like the right choice.

Based on my understanding, sodium metabisulfite is primarily used as an antioxidant in parenteral formulations to prevent degradation of the active ingredient. I think option A is the best answer, but I'll double-check my knowledge just to be sure.

Wait, I'm a bit confused. Is sodium metabisulfite used as an emulsifier in some cases? I'll need to review my notes to make sure I'm not missing something here.

Okay, I remember learning about this in class. Sodium metabisulfite is added to parenteral formulations to prevent oxidation, so it's acting as an antioxidant. I'm confident that A is the correct answer.

Hmm, I'm not entirely sure about this one. I know sodium metabisulfite has some stabilizing properties, but I can't recall if it's specifically used as a chelator, solubilizer, or cosolvent. I'll have to think this through carefully.

This one seems straightforward. Sodium metabisulfite is commonly used as an antioxidant in parenteral formulations, so I'll go with option A.

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?

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