Chemistry 1B Laboratory
Safety Document (All Students must sign and turn in on first day)
Gases Experiment
Turn in the duplicate copies from your laboratory notebook. These should include the procedure, data tables, and calculations. This is due at the end of the period of the second lab session. Make sure that your calculations are shown for each step and that significant figures and units are correct.
Vaporization
Read the Vaporization experiment and prep the abstract and procedure in your laboratory notebook. Record all data and calculations in your laboratory notebook (you should copy the illustrated tables in the handout into your lab notebook for this one). Turn in the duplicate copies from your lab notebook showing all data and calculations at the end of the second lab session. Be sure to include the graph from day 1 and from day 2.
Green Crystal
Read the experiment and prep the abstract and procedure in your laboratory notebook. Record all data and calculations in your laboratory notebook, BUT this time, please do print up the data tables and calculation tables from the handout.
For the report turn in the printed data and calculations worksheets through the empirical formula of the green crystal, plus the duplicate copies from your notebook containing data.
Kinetics Experiment
Read the Kinetics experiment and prep the abstract and ENTIRE procedure in your laboratory notebook. Different groups will be working on different parts of the experiment. Record all data and calculations in your laboratory notebook (you should copy the data tables in the handout into your lab notebook for this one). You will be turning in your lab notebook duplicate copies as well the Excel spread sheet and graph. Don’t forget to calculate the activation energy.
In addition to reviewing the usual procedure handout before lab, you may want to print these pipet charts for your own reference during lab.
Spectro Kc
Read the Kc experiment and prep the abstract and procedure in your laboratory notebook. Record all data and calculations in your laboratory notebook (you should copy the illustrated tables in the handout into your lab notebook). We will complete the entire experiment in one day.
On the second day we will create a spread sheet to find the initial concentrations, equilibrium concentrations, and the Kc for each trial. For your report submit the spread sheet along with your duplicate copies to your lab notebook.
Ka of a Weak Acid
Read the Ka experiment and prep the abstract and procedure in your laboratory notebook. Record all data and calculations in your laboratory notebook (you should copy the illustrated tables in the handout into your lab notebook).
Follow the calculations as outlined in the handout. Record these calculations in your labnotebook and turn in your duplicate copies for the report. MAKE SURE THEY ARE NEATLY WRITTEN!
Kin of an Indicator
Read the Kin experiment and prep the abstract and procedure in your laboratory notebook. Record all data and calculations in your laboratory notebook (you should copy the illustrated tables in the handout into your lab notebook).
We will create a spread sheet as outlined in the handout. For your report submit the spread sheet along with your duplicate copies to your lab notebook.
Solubility of Calcium Hydroxide
Read the experiment and prep the abstract and procedure in your laboratory notebook. Record all data and calculations in your laboratory notebook (you should copy the illustrated tables in the handout into your lab notebook).
We will create a spread sheet as outlined in the handout. For your report submit the spread sheet along with your duplicate copies to your lab notebook.
