Solubility Rules and Net Ionic Equations Sabrina Pietrovicci 12/01/17 Chemistry 1083*02

Objective: The main purpose of this lab was to observe the precipitation reactions, acid and base solutions. Then, describe the change of each solution according to the solubility rules and write down chemical equations describing the watched reactions.

Procedure: Testing the solubility rules For the first part of our experiment we watched the solutions to see what it formed according to the solubility rule. To begin our experiment we took a 24-well plate and washed it with distilled water to clean out all the plates. In just one row, we put 5 drops of NH4NO3, than row 2 through 5 with 5 drops of Ba(NO3)2, AgNO3, Pb(NO3)2, and Ni(NO3)2. For the next part we took 3 drops of chemicals including NaBr in column A,Na2SO4 in column B, NaOH in

column C, and Na2CO3. Looking at the chart below you can see the results of each plate.

Reactions with Acids and Bases In the last column of plates we placed 5 drops of 2M HCl in the first plate, 2M HC2H3O2 in the second, 2M NH3 in the third, and 2M NaOH in the last. We than placed red and blue litmus papers into each solution and observed our results which are shown below.

The last part of the procedure we put 5 drops of 2M HCl into the only row labeled C and if they was any change in the solution.

Conclusion: This procedure was easier than I thought it would be. It was very tricky finding the solutions in the lab due to the labels on the bottles being washed and worn off that we were barely able to see the names. Other than that looking at our results we had a pretty good results and seemed to not make any errors.
