Chemistry 28 March 2013 Identify and Unknown Ionic Compound ILI#3 Abstract: In this laboratory investigation‚ 8 solutions were combined with each other and an unknown liquid #1 in order to identify the ionic compound in the unknown solution. The students performed an experiment in which the reactions between each substance were compared to the unknown solution #1’s reactions and the color of each solution was compared to help find the unknown #1. The unknown ionic compound was identified to be

identify the unknown solution used in this experiment. In this experiment the methodology used by the group is to perform the tests for both the unknown and the cations (Ba+‚Sr2+‚Ca2+‚ Mg2+ and NH4+) using the known as a control for comparison and identification of the unknown used. The unknown used in this experiment by this group is unknown # 9. The result obtained from this experiment shows that the unknown contains Ca2+‚ Mg2+ and NH4+cations.The test made for Ca2+ both on the unknown and the control

Extraction and Evaporation. Separating the Components of “Panacetin” Introduction: The problem proposed in the experiment is an unknown ingredient found in generic Panacetin tablets that must be discovered. Panacetin tablets are known to contain aspirin‚ acetaminophen‚ and sucrose; therefore‚ the tablets tested‚ containing aspirin and sucrose‚ are thought to contain an unknown of something similar to that of acetaminophen such as acetanilide or phenacetin. Another problem trying to be sought out in the

Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula

sending you back to 1869 to see if you can recreate a periodic table as Mendeleev originally did by grouping together elements with similar properties and looking for trends within each group. If you are successful‚ you will be able to identify the unknown elements. Part A: Examining properties and trends. You will separate the elements into piles based on different properties. DO NOT put the cards back together until the end of Part A. You will have many piles by the end. 1. Sort the cards into

Experiment: 10/14/08 through 10/30/08 Date of Report: 11/7/08 Chem 2262L � I. Introduction In this experiment‚ the zinc and nickel contents of unknowns were tested using two methods. In the first method‚ nickel and zinc were separated through ion-exchange chromatography and analyzed through chelometric titration. In the second method‚ the unknown was analyzed through the atomic absorption spectroscopy (AAS) of the mixture. In and ion-exchange column‚ the ions are separated due to their tendencies
