Tuesday, Dec 5 Separations. Thursday, Dec 7 Read Ch 23, do pr. Because of the accuracy and precision required in careful analytical work, almost everyone can expect at least one lab result to be poor. You will be allowed to submit one recalculation for each unknown, but the final grade for that experiment will be the average of the original grade and the resubmitted grade. You will be allowed to redo experiments as time permits at the end of the semester.
Students can begin any lab after the pre-laboratory lecture is given.
In order to make sure everyone is making progress in the lab and not spending an excessive amount of time on one lab, the grade for a lab will be dropped by one letter grade for each week it is late. The schedule of prelab lectures and due dates will be announced in class in a timely fashion and posted on the lab door. The labs will go much smoother if you read the labs in advance, make sure you understand the procedure, and answer any pre-laboratory questions.
