Re: Chem Lab C
Acids and Bases has a lot to do with solutions so I would have some basic knowledge of Acids and Bases. Probably don't need to worry about Buffers and Acid Base equilibrium.lllazar wrote:So i know this event is focusing on Redox reactions and Aq solutions this year, but is there anything else that may show up on the test?
We had some Acids and Bases stuff on our state test last year. It was pretty much just identifying characteristics of acids.

Re: Chem Lab C
according to the ever sacred rules, it just seems that you must be proficient in Aqueous solutions and Redox. each accounts for 50% of the score.
also, students MUST wear long sleeve shirts

Re: Chem Lab C
looking at the test on soinc, i suppose you should know about pH, pOH, [OH-], [H+] and their relationships for acids and bases...

Maybe for general chemistry, but I don't think it's necessary for the main two topics.2win wrote:Oh, do we have to know about autoionization too??

Re: Chem Lab C
Two questions: 1. What would the actual lab portion of this event be like? What are the different things we might have to do? 2. From your prior experience at various competitions, is an AP level understanding of most of the subjects that may be covered adequate?

Re: Chem Lab C
I have a question about oxidation numbers. I know that they're assigned to different chemicals and ions and such, but how can you ever remember them? I tried to memorize them and I simply couldn't. Does anyone have a mnemonic device or something similar?
ALSO: Half-reactions. I don't understand them. Please help?

Re: Chem Lab C
You don't have to remember all of them, mainly just oxygen's and hydrogen's. There's formula to figure them out... the only things you have to memorize are the rules (aka exceptions to the formula)...
