ChemLab - Chemistry 3/5 - Qualitative Analysis of Anions

Bring your lab manual, your notebook with your completed prelab, a pen, your safety goggles, and glasses, if you wear contact lenses. If you are wondering where to get these things or what to put in your prelab, see the Info Section of this website.

Question 2

Help! I can't do the prelab problems!! What should I do?

Professor Milde

First, take a deep breath and calm down. It may help you to carefully read the information in the lab manual about the experiment and to consult the sections of your textbook listed under "To Learn or Review". There are also TA office hours, where you can get help from General Chemistry TAs. The time and place of TA office hours will be announced in lecture and is given on the Personnel page of this website. You can go to any office hours, not just the ones when your TA is on duty.

Question 3

What should I study to prepare for the Safety Quiz?

Professor Milde

It's more of a scavenger hunt than a quiz. You will label the map in your manual with the location of safety equipment, in the lab, while looking at the equipment. Then you will tear it out and give it to your TA. No studying is needed for the quiz.

But you do need to prepare for lab by doing the prelab problems, writing a procedure, and looking at the website. This way you will be ready for the experiment.

Question 4

What is the chemical formula for chalk?

Professor Milde

To quote the lab manual, "Eggshells, seashells, chalk, and limestone are some of the common substances containing carbonate." The formula for calcium carbonate is CaCO₃.
