- What about LADS G.1 and G.2 that were done on Sat?
- G.2 due on Wed (if you are really stuck and need to ask questions on Tues, you MUST email to let me know about that, to avoid a late lab)
- G.1 due on Thurs (need to ask questions? email me as to what you need to go over do it in class on Tues or Wed)
- These LADS will go in a quiz grades and as an added bonus, one of them will be banked as a free opportunity to drop your lowest quiz grade
- Those of you that did not get to do the LADS on Sat, have until Fri to actually do the LAD and it will be due by Mon (at the very latest)
Tues Jan 24 - Extra help available, sign up in class.
In Class we did,
- LAD G.1 − calculating molarity of NaOH solution (also to be used in G.2) (P1, KS)
- clarify Post LAD question 2d (P4 HG)
- clarify Post LAD question 7 b (P1 KS)
- LAD G.2 −
- review PRELAD quest # 2 & 3
- clarify Post LAD question #4b
- Polyprotic acids − what are they? writing multiple dissociation rxs, using k values to calculate pH (P1 SH)
- How to know about SA or WA dissociation (and other?) (P1 MB)
- Using Kw to calculate a Ka value (suppose we wanted to calculate pH of a salt?) (P4 KT)
- Calculating pH of a weak base, #51c (P1 ILS)
- Quiz Acids/Bases
Outside of class you should,
- Read sect 16.9 (pgs 641−644) do sample problem 16.18 AND problems at back of chapter (pg 656) #s 73 and 75
