I don't know about you guys, but I'm just hoping the exam doesn't ask about the density of the suspension particles. That's when I'll really be in trouble!

B) the use of a pH buffer system? What is this, a chemistry class? I'll stick with the good old settling particles, thank you very much.

A clear solution? Really? That would just mean the components are compatible. This exam is trying to trick us, I tell ya!

Yeah, I agree. We have to watch out for unexpected changes in odor or particles settling at the bottom.

I think you're right, a clear solution doesn't necessarily mean compatibility.

I was leaning towards C) an unexpected change in odor, but I guess D) makes more sense. Gotta keep an eye out for those pesky settling particles!

I'm not sure, but I think D) suspension particles settling to the bottom of a container could also be a sign of incompatibility.

I agree with Marg, because a change in odor could indicate chemical reactions.

D) Suspension particles settling to the bottom of a container seems like the obvious sign of incompatibility. The other options don't really indicate incompatibility in my opinion.
