On-Line Lab Manual

Experiment 1

Laboratory Notebook/Prep

Please read the introduction to the Experiment A1-Measurements lab.  There is no lab prep for this experiment, but a worksheet regarding significant figures will be handed out.

Laboratory Report 

Print and turn in the worksheets that are provided in the on-line lab manual pdf for this experiment (Complete the data tables, calculations and PRINTED graph (make sure to include the linear regression and equation for a line) ).  Make sure to show one sample calculation for each type of calculation performed.  This report will be due at the end of the lab period.  

Experiment 2 

Laboratory Notebook/Prep

Please read the introduction to the Experiment A2-Nomenclature lab.  There is no lab prep for this experiment.

Laboratory Report 

Print and turn in the worksheets that are provided in the on-line lab manual pdf for this experiment. 

Experiment 3

Laboratory Notebook/Prep

Read Experiment A3- Hydrate lab found in the on-line lab manual (link above). Prepare the abstract and procedure in your laboratory notebook as discussed in lab and as outlined in the syllabus. Staple your duplicate copies from your notebook and turn them in at the beginning of class.

Laboratory Report 

Illustrate one set of sample calculations for both the known and unknown in your laboratory notebook as discussed in class. Report the pertinent information for the other three trials of the known and unknown. Also, answer the questions that were provided in class in your laboratory notebook. Turn in the duplicate copies of your data tables,  calculations and questions on 10/10/19. 

Experiment 4

Laboratory Notebook/Prep

Read Experiment A4- Precipitate lab found in the on-line lab manual (link above). Prepare the abstract and procedure in your laboratory notebook. Staple your duplicate copies from your notebook and turn them in at the beginning of lab.

Additionally for this experiment you will need to PRINT PAGE 9. All other data and calculations will be recorded in your laboratory notebook. 

Laboratory Report 

You will have Page 9 signed off in lab for Part I.  For Part 2 perform the calculations as described in class and complete two required graphs using Excel or a similar program.The calculations and conclusion (answer to the questions regarding the graphs) should be done in your laboratory notebook.  Turn in Page 9 and the duplicate copies of your data, calculations, graphs, and conclusion.  

Experiment 5

Laboratory Notebook/Prep

Read Experiment A5- Reactions lab found in the on-line lab manual (link above). There is no notebook lab prep for this experiment; however, on a separate sheet of paper briefly type up the answers to the following three questions. 

1) Give an example of a double displacement reaction.

2) Find the solubility rules in your textbook.  Which types of ionic substances are generally insoluble?  Which types of ionic substances are always soluble?

Experiment 6

Laboratory Notebook/Prep

Read Experiment A6- Conductivity  lab found in the on-line lab manual (link above). There is no notebook lab prep for this experiment.  Print up the worksheets and data tables. Answer the following questions for your pre-lab. Type your answers on a separate sheet of paper.

1) Indicate whether the following are strong, weak or non electrolytes: CH3CH2OH, H3PO4, HCl, C2H6O2.

2) Write out equations for the dissociation of of NaCl (aq), CaCl2 (aq), and AlCl3 (aq)

Laboratory Report

Experiment 7

Laboratory Notebook/Prep

Read Experiment A7- Titration lab found in the on-line lab manual (link above). Prep this lab in your laboratory notebook.  All data and calculations will be placed in your laboratory notebook. Make sure that the duplicate copies are clearly legible because these will be turned in with you typed written full report.

Lab Report

The calculations for this experiment are completed and turned  in at the end of the lab period.

Experiment 8

Laboratory Notebook/Prep

Read Experiment A8- Calorimetry lab found in the on-line lab manual (link above). There is no notebook lab prep for this experiment.  Print up the worksheets and data tables. Answer the following questions for your pre-lab. Type your answers on a separate sheet of paper.

1) Write out the three reactions that occur in the first part of this experiment with NaOH and HCl.  One of the reactions is only the dissolution of NaOH(s) in water.

2) How might the enthalpy change in this experiment be different for a weak acid versus a strong acid? (Hint: Would you expect the reaction of a weak acid with NaOH to be more or less exothermic than NaOH and HCl?)

Laboratory Report

Experiment 9

Laboratory Notebook/Prep

Read Experiment A9- Redox titration lab found in the on-line lab manual (link above). Prep this lab in your laboratory notebook.  All data and calculations will be placed in your laboratory notebook. Make sure that the duplicate copies are clearly legible.

Laboratory Report

The calculations for this lab may be done in your notebook. Also make sure to indicate what is oxidized/reduced and the oxidizing agent/reducing agent for the four equations presented in class.  The duplicate copies of the data and calculations will be turned in on the Monday after completing the wet chemistry.
