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!

Today, we started class by going over the quiz.

Heads up! There will be a quiz on an ICE problem tomorrow. Be ready for anything, I suggest. There is also a web assign due tonight as per norm.

After that, we went over the homework.

Two important notes:

-In these ICE problems, the concentrations of H3O+ and OH- are very important!
-Small zero rule is always a good choice! (btw. In the small zero rule, you take out the x that is either being added or subtracted)

We went over 9a and 10a.
9a. Concentration of H3O+ should be .000035
10a. Concentration of OH- should be .003

Mrs. Friedmann will post up the key on Moodle.

On that note.
GOOD JOB HONORS ENGLISH STUDENTS! WE MADE IT!

Next blogger will be Elaine Sine.
