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 :)
I just reviewed the rules, and it said nothing about using sig figs, I think my brain is just wired like that at this point LOL. Thanks so much, congrats for finishing 2nd!

I didn't know this till now but Scioly changed wild carrot to western water hemlock? 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?

Galahad and I, towards the start of the season, were confused about the presence of the wild carrot in the rules. I did a little research and told him that it isn't harmful and that he shouldn't study it and instead study the water hemlock because they look alike.

So the answer to your question is they look alike and there seems to have been a miscommunication about Daucus and Cicuta. They resemble one another, explaining why the species were confused even though they are from different genera. I have no clue why they changed it after so much of the season has passed, but I'm not blaming them because stuff like that happens. And the main reason for the change is because the wild carrot isn't poisonous and the water hemlock is.

im pretty sure that the wild carrot is toxic to farm animals and such and can cause slight burns to people because of cell sap. Am i wrong?

Yeah you’re correct. I guess it’s just not toxic enough lol

Hey, I just need to check. how many pages of notes can we take to state?
thx!

Hi,

My state tournament is next week, and I was wondering to what extent ESs tend to test participants on conductivity testing. I know it's in the rulebook, but I haven't heard of anyone who got tested on it. I'd also like to know how to do that, so it'd be great if anyone could give me an explanation :)

Heh, funny story...

Being in Hawaii, we don't have much of a picture about how we are against other teams across the nation, so we plan an annual trip to California for an invitational. Last year, I did Potions. When we were packing our kits (we have two teams) we found that we had only one conductivity tester. We debated and our Potions coach decided to give it to the other team because they were less experienced.

Lo and behold, our lab was conductivity and, as no one in the entire school was good in chemistry, I didn't know that I could use pH paper to determine conductivity.

Long story short, we got a goose egg on the lab and were one place below the other team, who botched up the lab. Also don't study exclusively for conductivity but be prepared.
