Identification of Unknown Organic Compounds Nicole Lueder Professor Z September 24th, 2015 Introduction: In this three-week experiment my partners and I were given two samples, one solid and one liquid and told to determine what compound we were given. Our unknowns will contain a functional group which should help us determine our compound. In order to determine our compounds, we will be using infrared spectroscopy and NMR. We will also find a melting point as well as a boiling point
The purpose of day one was to identify the unknown white compound. The chemicals used the 1st day of the lab contain 1mL of 0.1M AgNO3, 6M HNO3, 6M NaOH, 0.1M BaCl2 and 1 mL of 6M HCl these chemicals were specifically chosen for the ion tests after the unknown dissolved in water, as mentioned on lab archives. In our entire experiment we used distilled water because routine tap water can produce many problems when used in sensitive lab like this. Distilled water is used because it is important to
Citizen by Claudia Rankine is a book that was published during a sensitive time in the United States. With controversial cases on trial and many protests taking place over the murders of African Americans by White law enforcement, Rankine reminds us that racism is relevant and alive. She uses poetry and several different elements throughout her book to push the reader into noticing the faults in their own actions, and in the actions of the people around them. Rankine points out everyday racism that
breaking free and travel the world. In fact, you ask anyone with a slightly compelling tone, and from the deepest corners of their hearts, even if it is for the sake of the moment, they would admit that they would like to take on that journey to the unknown. For most, the chapter starts and ends with the thought at the same place, for traveling the world is a challenge not everyone dares to undertake! It is only a few, a rare breed called the travel bloggers, who do it right on the face, against all
Museum of Art, Nevelson vertically and horizontally stacks wooden boxes filled with abstract wooden scraps one on top of another. Evoking the feeling of a brick wall, Nevelson shows how even when there seems to be a barrier sectioning off parts of the unknown, there is somehow a way to explore what is beyond the said barrier. This is why Nevelson’s use of the word “worldscape” over landscape is so important. It emphasizes the importance of thinking about the bigger picture, rather than just simply accepting
Purification and Identification of a Solid Compound Sara Dutra September 28, 2015 The first objective was to purify benzil using recrystallization and to determine the melting point of the pure benzil as well as the impure benzil. The second objective was to purify an unknown compound using recrystallization and to identify the unknown compound using its melting point. Compared to the melting point of a pure substance, the melting point of an impure mixture will have a larger range and will melt
The goal of the experiment was to identify the unknown compound by investigating both the chemical and physical properties of it. By performing various tests we were able to further discover the properties of our unknown compound. Through process of elimination we were able to rule out potential compounds by comparing our results to our research of other compounds. We determined the quantitative solubility of our compound by dissolving it in water until the solubility capacity was reached. By finding
engineering Title: Determination of concentration for unknown solutions of nitrite and phosphate. Author: C. SUNGKUR Student id: 1615715 Date of submission: 20/10/2016 Submitted to: Mr. Y.SEECHURN ABSTRACT When primary aromatic amine and nitrous acid react together, it results in a diazonium compound and this process is called diazotization. In this experiment, we are asked to find out the concentration of unknown solutions of nitrite and phosphate. In order to perform
proportional to the amount of protein in the sample. Thus using Beer – Lambert law, the concentration of protein is estimated by measuring the absorbance of standard concentrations, plotting the standard curve using a least square error fit and plotting the unknown concentration on the curve. The reagent is added to the sample and incubated for 30min in room temperature. The absorbance is measured at 450nm, and the concentration is determined by the use of beer-lambert law. This reaction is the first step
When a solution of an inorganic salt such as sodium chloride is sprayed into the flame, the elements in the compound are partly converted into the atomic state. Due to the heat energy of the flame a very small proportion of these atoms is excited and the electrons move to a higher energy level. The proportion of the atoms that are excited depends upon the concentration
