Qualitative Lab Report
The Qualitative data collection and observations were successfully used to determine the types of reactions between known cations with known solutions in order to determine unknown cations in an aqueous solution by comparing the reactions with the known solutions. When a distinct characteristic of a light purple precipitate was formed from the combination of cobalt and sodium chloride, sodium chloride was used to determine that the purple precipitate formed when tested with the unknown cation meant that the unknown cation contained cobalt as well. After determining that the lead cation made a distinct, bright yellow precipitate when combined with potassium iodide, the potassium iodide was combined with the unknown solution also creating a bright
