Abstract
This experiment is designed to study the nature of ionic reactions, and write net ionic equations for precipitation reactions, as well as to identify spectator ions, perception reactions and solubility of different compounds.
Experiment and Observations
In this experiment I was using a 96-well plate to add two drops of the following solutions into seven wells in rows A through E: cobalt (II) nitrate, copper (II) nitrate, iron (III) nitrate, barium nitrate, and nickel (II) nitrate. Afterward, two drops of each of sodium phosphate, sodium iodide, sodium sulfate, sodium chloride, sodium bicarbonate, sodium carbonate and sodium hydroxide were added to the five vertical wells under columns 1-7.

Analysis of Results & Conclusion
Based on the solubility rules my results proved accurate. Just by looking at the solubility rules, my results were what I expected them to be. I found that sodium chloride did not react with any of the five
