1. Ionic Bonds
Molten salts and aqueous solutions of salts are electrically conducting. This conductivity results from the
motion of ions in the liquids. It suggests the possibility that ions exist in certain solids, held together by
the attraction of ions of opposite charges.

Find the nearest nuclear power plant and in your 200+ word post, answer the
following: South Texas Nuclear Generating Station
https://en.wikipedia.org/wiki/South_Texas_Nuclear_Generating_Station a. What is the name of the plant? b. Where is it located and how close is it to you? c. What are your thoughts about living this close to a plant? d. What are the advantages and disadvantages to nuclear power? 3. Cations and Anions Reaction Lab Laboratory Details All labs will have pre-lab comments found within ANGEL. You will
learn of any changes in the lab in the pre-lab comments. These changes take
precedence over what is found in the lab.
For you to get an idea of real lab techniques, you will find some video
links to laboratory videos. All lab reports must be in MS-WORD. You must include the
"observation sheet" as a table within your lab report for this first lab.
As in any beginning laboratory in an introduction course, you begin by
learning some of the basics. Here, you will learn about selecting instruments,
chemicals, pouring and decanting. FYI: “Decanting” means pouring off a liquid without
disturbing the sediment or lower liquid layers. If you Google the word, you will find
that decanting is important in separating the sediments from an old bottle of wine.
The following website will show you to some interesting laboratory
techniques

Reaction between cations and anions will be examined in this lab. The resulting
precipitate is indicative of the reaction that occurred.
Now what do you do?
1. Open ChemLab and select “Cations and Anions
Reaction” when prompted. 2. Read through the Introduction in BOTH the course and
in ChemLab. Some labs include some modification from
the ChemLab instructions and if so, these modifications
will be listed in our course with each lab. 3. Watch the intro video for the lab: https://content.grantham.edu/at/CH205/labs/CationandAnionLab.mp4
1. Follow the Procedure as outline in ChemLab. 2. Perform the lab, collecting the indicated data as noted in the
observations section (create your own data table within your lab
report collecting the specific data from this list). 3. Perform the various calculations with your collected data as listed in
the lab’s observations section and a. Note in your lab report the identity of the precipitate formed.
b. include the complete, balanced molecular equation for the
reaction between the two reactants Pb(NO3)2 and K2CrO4,
c. the complete ionic and the net ionic equations.
d. calculate the theoretical yield (using the starting quantities of both
reactants)
e. calculate the percent yield (based on the recorded weight of your
product at the end of the experiment). Be sure to show how you
obtain both for full credit.
4. Write a lab report of the lab within MS Word. (There is a “Sample
Lab Report” and “Lab Report Instructions” files in week 1’s course
folder).
