Quiz 3 material (16.1-16.11, 17.1-17.2) - Tuesday, July 2

[robert zellmer]

Quiz 3 will cover the following:  Chapter 16 (16.1-16.11) and Ch 17 
(17.1-17.2)

This is pretty much up through last Monday.  It covers all of chapter 16
and the first two sections of 17.1-17.2 (common-ion problems and buffers).

Rather than repeat it all here, you can find details of what's covered on
the quiz on my web page by going to the "*Quizzes 
<https://www.asc.ohio-state.edu/zellmer.1/chem1220/quiz/quiz_1220.htm>*" 
link at my Chem 1220
class web page (not Carmen). It also lists which sections from the textbook
are covered and the corresponding end-of-chapter (EOC) problems and on-line
homework which you should be able to do.  There's also further descriptions
of things there and links to other help files for this material which can be
found on my web pages.

On the quiz, if you need to use an ICE table, you must show the work
and the ICE table. When making any assumptions you should show that
your assumptions are okay (less than 5% error). If the percent error
is greater than 5%, you need to solve the resulting quadratic equation
or use the method of successive approximations (both shown in class
and in the notes). You must show this work. If you don't, you will not
get full credit. Simply showing the ratio of K_a /[HA]_o < 10^-3 is not
sufficient (similarly for a base using K_b and [base]_o ).

We finished section 17.3 (titrations) and are about halfway through 17.5.
Titrations and the solubility material from sections 17.4 and 17.5 are
NOT on the next quiz.  However, you want to try to get to this material,
particularly titrations, so you can get caught up.
