You should probably bring 1 of each. If it was really necessary, the proctors would probably provide it.

Based on the last two years, we've had;
chromatography (rarely, but be ready)
mixtures of reagents/ separation of a mixture
serial dilutions (with vinegar)
determination of pH
conductivity testing (not really though)
physical vs chemical changes
The ES would use either one or even all of them. Be ready for all. : )
Yeah, except I've personally never seen chromatography.

There was actually a Potions and Poisons chromatography portion in the recent Garnet Valley Invy!

I responded with “0.045g/mL” then I realized sig figs exist. Am I supposed to use sig figs in this case? There was a follow up question that asked for the volume of the two solutions, so having the same concentration means they have the same volume, which isn’t very accurate.

I asked my coach and she said possibly, but probably not if it didn't say it explicitly in the directions, and to ask the proctor to double check. Btw congrats on going to states! My team just finished 2nd place at our regionals yesterday and I won Potions

They consider this a "clarification" but they're literally 2 different species in two different species, how do they get it wrong after many of the invitationals have past?? What would be the reasoning behind this change?
