The purpose was met for this experiment because we predicted the products of chemical reactions and we wrote out the net ionic equations. Lead Iodide should be a yellow, insoluble in water, precipitate and that is what we created in the experiment as you can see in the picture. Silver Chloride should be a white, insoluble in water, precipitate and that is what we created in the experiment as you can see in the picture as well.

# data[].attributes.body
Silver Chloride's net equation is 3Ag(+)(aq) + Cl3(-)(aq) → 3Ag(+)Cl3(-)(s). While researching, we found that our product from the lab matches what the background information. Our results are validated by a slight color change, along with the formation of a solid, which is the Silver Chloride. Also, our net ionic equation matches what we found in the background research.

The net ionic equation, as stated above, is Pb(2+)(aq) + I(-)(aq) → Pb(2+)I(-)(s) for Lead Iodide. The product from the lab does match the expected product that was found in the background research. Our results were validated due to the obvious yellow color change that was shown to be very consistent in this mixture.

# data[].attributes.body
For this reaction in the experiment, it was clear that a chemical reaction had taken place. There was a very slight color change to white and it was obvious that a precipitate had formed. This was due to the formation of silver chloride creating white chunks at the bottom of the well.

(This reaction can be seen in the picture to the right, along with well A2 on the "Well Plate" photo from our lab worksheet.)

The biggest indicator that a reaction had taken place was a color change from clear to bright yellow. Also a precipitate was formed at the bottom. This bright yellow color, along with a slight precipitate, was created because of the lead iodide mixture that was formed in the well.

(This reaction can be seen in the picture to the right, along with well D3 on the "Well Plate" photo from our lab worksheet.)

A 24 well plate was prepared for the experiment and all of the chemicals and other materials were collected in order to begin. Once it was ready, the pipet was used to drop 2 drops of each solution in its designated well, while holding the pipet vertically. Then, each mixture was stirred with a clean toothpick. On the lab paper, the results were recorded by putting "R" for reaction and "NR" for no reaction in each well on the well plate template. The well plate was then photographed. The contents were then dumped down the sink and the well plate was cleaned.

Double Replacement Reactions: a type of chemical reaction where two compounds react, and the cations and the anions of the two reactants switch places, forming two new products.
Insoluble Salt: Do not dissolve in water. Also known as a precipitate.

Lead Iodide:

Should be a yellow crystalline solid that is insoluble in water (https://cameochemicals.noaa.gov/chemical/3741 ).

Uses: Printing, photography, to see clouds, batteries, bronzing, and special gold applications (https://cameochemicals.noaa.gov/chemical/3741 )  (https://hazmap.nlm.nih.gov/category-details?id=2524&table=copytblagents )

Silver Chloride:

Should be a white crystalline solid that is insoluble in water (http://www.softschools.com/formulas/chemistry/silver_chloride_uses_properties_structure_formula/293/ ).

Uses: Preparation of photographic films, phototchromic lenses, infrared windows, pottery glazes, and stained glass.  Also used for disinfectant like in wound healing products, water treatment, and for mercury poisoning (http://www.softschools.com/formulas/chemistry/silver_chloride_uses_properties_structure_formula/293/ ).
