This is all I have so far I don't even know if it's right or whether the cm^3 apply
You should try to see if you can find a definition for this term, it means something, but what, and if its pertinent, will depend on the situation. Your textbook, or class notes, or even if you're bold, just ask the instructor: "What does this mean?"
Beaker 1: KMnO4 + Na2S2O3
Beaker 2: KMnO4 + Na2S2O3 + BaCl2
Beaker 3: KMnO4 + BaCl2
Beaker 4: KMnO4 + Na2S2O3 + Na2CO3
Not bad. Or forum has subscripts, that'd make the display neater. But go ahead and save that for the next time.
I really don't know much as we haven't touched on any of this yet
If this is an experiment to be done, they may have hoped you would look it up, and not go in the lab blind. You've had a hint from us -- we've identified oxidizing and reducing agents. See if you can find a hint in your textbook, and have something to talk about in lab.
