Introductory Chemistry 1110 Qualitative Analysis Using Precipitation Reactions Lab reports are due week of September 29 – October 3, 2014. Your lab report must contain the following information: Experimental data may be collected with other students in introductory chemistry labs. However, I understand that sharing information required for a lab report or unknown submission (including but not limited to word processing or spreadsheet files, calculations, graphs, conclusions and additional problems at the end of the lab report) with other students is a violation of the University Academic Integrity Code. ¬¬¬¬¬¬¬¬¬¬¬¬¬¬_____joneshattonj@email.appstate.edu________________________________ Signature (or ASU email address, to indicate signature if an electronic copy is submitted) Introduction: Qualitative analysis is the use of experimental processes to identify the chemical parts of a substance. The knowledge of the meaning of soluble and insoluble is key to completing this experiment correctly and accurately. Soluble means that a compound readily dissolves in water and insoluble means that compounds do not dissolve in water. A precipitate is formed when two soluble compounds combine to form an insoluble compound. All nitrate solutions are soluble; therefore, the known solution was formed by dissolving nitrate salts of all the cations in the experiment in De-Ionized water. A centrifuge was used in each step of the experiment to spin
