Chloride

In this experiment, qualitative analysis was used to identify two cations. Lead was identified in Part A, barium was identified in Part B and different flame colors were observed with various metal chloride solutions in Part C. Formula unit, total ionic, and net ionic equations were written for the confirmation reactions for both lead and barium. If this experiment was repeated, barium could be confirmed by the yellow precipitate BaCrO4 after confirming that the solution was clear and any…

Purpose: The objective is to separate the heterogeneous mixture of salt, iron filings, and salt into each pure form using filtration, evaporation, and magnetism. Background: When separating a mixture, preferably to separate a mixture that includes a soluble liquid and a insoluble solid, filtration is the best because solid molecules are bigger than liquid molecules. A filter contains pores that are small enough to let small partials though the pores while holding back the larger particles.…

based on temperature or solute concentration. The determination of precipitates also come from solubility rules. According to Cooper, almost all sodium, potassium, and ammonium salts are soluble which mean that they will not form a precipitate.1 All chlorides, bromides, iodides, and fluorides, nitrates, chlorates, perchlorates, and acetates, and sulfates are also soluble. The only exceptions are as follows: Ag+, Hg2+, Pb2+, Mg2+, Ca2+, Sr2+, Ba2+, Pb2+. For week three, the goal was to determine…

our environments so is that salt that was previously used to treat the roads (Gould, 2013). Roadside vegetation can become injured or die to due to the runoff from the treated pavements (Gould, 2013). The salt used for treated pavements is usually chloride-based and is applied to roadways, driveways, sidewalks, and highways to melt ice and snow to ensure safety for pedestrians as well as motorists (Gould, 2013). To improve traction de-icing salts can often be mixed with abrasives such as sand,…

Innervisions, and is called Acamar, written by a duo called Frankey and Sandrino. The record is presented in a black inner sleeve with a fantastic artwork print, information sheet and elegant outer sleeve. To many, it is merely a slab of polyvinyl chloride nestled within a nexus of card, paper and minimalist design.…

Every year during winter months, icy surfaces create a dangerous problem for drivers and pedestrians. Icy roads and sidewalks can become very hazardous for travel. A solution must be implemented to mitigate risks associated with winter travel. This problem is relevant to the experiment since I will be testing different methods of melting ice. The solution resulting from the experiment can be used throughout the world to make our roads safer. The literary reviews for this experiment are from…

CSX Train Derailment and Hazardous Leakage On May 1, 2016, a CSX freight train derailed causing a possible spill of the chemical contents it carried. According to the District of Columbia Fire and Emergency Medical Services department (DCFEMSD), the derailed train in northeastern Washington DC resulted in the leakage of hazardous chemical material by three cars (Washington, 2016). The total amount of cars sent outside the railroad in the derailment incident was however, confirmed to be 14…

the charges of the solvent. For instance, sodium chloride dissolves in water because the sodium cation has a positive charge and the chlorine anion has a negative charge. The water molecules also have partial charges because the oxygen is more electronegative than the hydrogen atoms, pulling electrons toward itself, producing a partial negative charge with a resultant partial positive charge on the hydrogen atoms. The charges between the sodium chloride and the water interact leading to a…

The experiment outlined by this lab report demonstrated the idea of synthesizing tert-butyl chloride through an SN1 reaction. The SN1 reaction took place with a polar protic solvent taking the place of the leaving group (alcohol) and creating a new replacement bond with the carbocation to form a tertiary chloride structure. The product was then tested for this structure by reacting it with two substances: sodium iodide and silver nitrate. These tests were to demonstrate that if the product…

The chloride test resulted in no evidence of a white precipitate, which pushed the team to conduct the sulfate test. During the sulfate test, the solution became cloudy, the unknown substance did not completely dissolve, and there was evidence of a white precipitate…
