Hi, class!  Given that we have not yet discussed buffers in detail in class yet, I have elected to move the deadline for the Buffers WebAssign to SUNDAY NIGHT, 11:59 pm.  The other WebAssign (on Kb and salts) is still due tomorrow night (Wednesday 4/23) by 11:59 pm.  By Thursday you should also have completed pages 10 and 11 in the packet...for those of you absent today a video of today's lesson will be posted by 7 pm tonight.  Quiz Thursday, during our 20 minute period (it will be a problem calculating the pH of a salt).

Happy ICEing!
