of an unknown compound. The compound was identified as calcium nitrate by a variety of tests. When the compound was received, it was already known to be one of twelve possible ionic compounds. The flame test identified the presence of the calcium anion in the compound. The compound tested positive for the nitrate cation using the iron sulfate test. At this point it was hypothesized that the compound was calcium nitrate. Reactivity tests and quantitative analysis comparing the unknown compound

Project 11: Identification, Properties, and Synthesis of an Unknown Ionic Compound Jacqueline Parker Chemistry 101 Laboratory, Section 10 Instructor: Xiaoyan Yang September 28, 2015 My signature indicates that this document represents my own work. Outside of shared data, the information, thoughts and ideas are my own except as indicated in the references. In addition I have not given aid to another student on this assignment. Discussion of Results The primary
techniques were used to purify and identify the product(s) of the reaction? In this experiment, an acid-base extraction was done to separate a mixture of an unknown acid and fluorene, a neutral compound. The possible unknown acids were 2-chlorobenzoic acid, 3-chlorobenzoic acid, and 3-methylbenzoic acid. The purification of the isolated unknown acid was performed by recrystallization and its identity was established by analyzing the melting point range of the pure product and comparing it to the provided
Identification of Unknown Organic Compound by Melting Point (M.P), Boiling Point (B.P) and Infrared Spectroscopy Methods and Background The main objective of this lab is to identify the given unknown organic compounds with various methods. Identification of an unknown compound is important to perform through the process of melting point (M.P), boiling point (B.P) and Infrared spectroscopy (I.R). Index of Hydrogen deficiency (IHD) and elemental analysis makes an experiment more efficient in
part of the Identification and Synthesis of an Unknown Ionic Compound (Project 3 Week 1) experiment was to determine the unknown compound #202 that is given to the experimenter. The second part to the experiment (Project 3 Week 2) was to discover different tests the experimenter can conduct in order to prove that they have the specific ionic compound that they discovered in part one. Some of the ways that the experimenter can determine the unknown compound #202 they have includes, preliminary tests,
Introduction A Cobalt-Amine-Halide compound is synthesized from cobalt (II) chloride hexahydrate. An orange-tinted solid is produced and is considered to be unknown since the specific ligand amounts are unknown. By determining the percent composition of various elements and compounds in the unknown, its true identity can be predicted. Chloride, ammonia, and cobalt are three examples of percent compositions determined to help narrow the selection of possible unknowns. Titrations using Na2S2O3 and HCl
Identifying inorganic compounds using qualitative analyses and chemical tests Jessica Vithayathil U84363206 CHM 2045L Section: 033 Aaron Clark October 13, 2016 Introduction Due to climate change during the turn of the 21st century and overall population growth, scientists have noticed greater amounts of negative impact on water sources (Barber, 2011). Waste Water Treatment Plants (WWTPs) have been identified as one of the root causes of stress for these water sources (Barber).
Data Analysis Identifying an unknown substance can be accomplished with the use of multiple scientific tests. Conducting these experiments will narrow down the possibilities of the unknown compound. The number of the unknown substance that I was given was A84841BIR, It posed to be a challenge since I needed to test three different molecular combinations for this specific substance. Once the number of moles the in substance was calculated using the ideal gas law, I divided it from the sample mass
predict the properties of compounds. Chemical formulas can be found by a process called gravimetric analysis in which components of a compound are isolated, their masses are found, and the mass differences recorded. Gravimetric analysis can be helpful when finding the formula of an ionic hydrate, an ionic crystal bound to water molecules because it allows for the mass of water to be found allowing for further separation of the remaining elements in the ionic compound. When water is removed from
