Ionic Reactions Lab
Lab Report Name: _____
Date: ______
Ionic Reactions
List all of the cations used:
Cobalt, Copper, Iron, Barium, Nickel
List all of the anions used:
Phosphate, Iodide, Sulfate, Chloride, Bicarbonate, Carbonate, Hydroxide
Compare your results with the solubility rules and/or solubility table in your chemistry text.
QUESTIONS:
A - Do your results agree with your expectations from the solubility rules/table? Yes, I feel my results agreed with the expectations laid out in the rules and table from the lab.
B - Which anions generally form precipitates? What are exceptions?
Precipitates: Most metal hydroxides and oxides.
Exceptions: Alkali metals, hydroxides and barium
C - Which anions generally do not form precipitates? What are the exceptions?
See solubility table/rules
Salts of nitrate and salts of sulfate.
D - Which cations generally do not form precipitates?
Cautions from row 1-2 had very few insoluble salts. They do not form precipitates. F - Select 5 reactions that produce a precipitate, color change, or gas and write balanced chemical equation below. Remember, a reaction may be indicated by the formation of a precipitate, color change, or the formation of gas. Record the well numbers of the precipitates you chose for your equations.
1A Co(NO3)2*6H2O when mixed with Na3PO4*12H2O the chemical combination turned Purple.
1B Cu (NO3)2 *3H2O when mixed with Na3PO4*12H2O the chemical combination turned light blue
1C Fe (NO3)3 * 9H2O when mixed with Na3PO4*12H2O the chemical combination turned a light yellow
1D Ba (NO3)2 when mixed with Na3PO4*12H2O the chemical combination turned white and the mixture sizzled when mixed.
1E Ni (NO3)2 * 6H2O when mixed with Na3PO4*12H2O the chemical combination turned a light foam
