Quiz 8 released, sample quiz up

[Zellmer, Robert]

I've released the quiz 8 results and the questions.

There's a blank sample "paper" quiz and the solutions to it on my
personal class web page at the "Quizzes" link.  For the titration
questions you might consider looking at the solutions, even if you
got the similar questions on the Carmen quiz correct.  I've added a
lot of "extras", i.e. explanations of how to calculate the pH at points
along the titration curve not asked for on the Carmen quiz.

Before asking me if there was a mistake in a quiz question check the
sample quiz and solutions to make sure you did things correctly.

Also, for numeric questions, if you're answer is close but outside the
allowed range please make sure you followed directions.  That means
did you use the constants as provided on the info/PT page.  Did you
carry extra digits from one step to the next in the calculations?  Did
you round to the correct number of decimal places as provided in the
question?  This seems to particularly problematic for pH questions
where people can get close to the correct answer when making
errors.

After that, if you think there might still be a problem or you just don't
understand something let me know.  You will have to provide the work
you did for the question showing all your work.

If you missed the quiz I suggest you download the sample quiz and take
it, timing yourself with the time given at the top of the quiz.  Then check
the solutions I've posted and "grade" yourself.
