Silver chloride

We then took a blue test strip of silver nitrate and placed it into a zip lock bag for our control. We would also take to additional blue strips and place one into a zip lock bag and begin respiration process of exhaling into the bag to test for the excretion of water. For part B we tested for the excretion of salt by rubbing a small piece of cotton in a clean palm, non-cleaned palm, and urine and then placing the cotton into a test tube. 5-6 drops of silver nitrate…

carbonate due to evolution of CO2 on addition of sulphuric acid. Among the soluble solids, two (1 and 12) formed precipitates in sulphuric acid. One was expected to be Barium chloride and to react with silver nitrate. Hence, (14) and (13) were reacted with 1 and 12. This led to the identification of 1 as barium chloride and 13 as silver…

asphaltum.” “Talbot understand how the percentages of silver nitrate to sodium chloride affected sensitivity.” (http://faculty.georgetown.edu/irvinem/theory/Osterman-Romer-history-of-photography-ex.pdf) What did Louise Daguerre and Nicephore Niepce contribute to the invention of photography? Louise Daguerre and Nicephore Niepce contributed to the invention of photography by Daguerre creating an image on a silver-plated copper, overlaid with silver iodide, and developed with mercury. Nicephore…

In experiment 2, we observed that the reaction of halogenoalkanes with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes…

chemicals (fluorine) and compressed gas (propane, CO2). Regarding this experiment, the there is always a possibility for mishaps and the like occurring that range from stains onto clothing to the irritation of the eyes. Chemicals such as copper (II) chloride and lead (II)…

Silver nitrate is a compound with many practical and non-practical uses. Like many other compounds, it is very helpful in discovering the many reactions that lie in our seemingly endless periodic table of elements. A few of the categories that utilize this compound are, laboratory work, manufacturing, biology research, medical history, photography, and even the art of ceramics. Silver nitrate has been known by scientists worldwide to be very helpful in detecting the presence of Chlorine,…

1. Obtain the mass of an empty 250ml beaker using the balance. 2. 200mls of silver nitrate was added to the beaker,…

Precipitation reaction, or otherwise known as double-replacement reaction, is one of the three common types of chemical reactions along with decomposition and combustion. A simple definition for the precipitation reaction would be “atoms from two different compounds switch places” (Lew 40). This means that one of the reactant’s molecule “trades” places with another from another compound to form products, like a precipitate, hence the term double-replacement. A precipitate is usually a solid…

The Identification of an Unknown Substance Using a Series of Tests Project 2 Chemistry 111 – 552 Peyton Farmer*, Primary Author Partners: Jacob Hicks and Abigail Boudreau TA: Ming Uei Hung Introduction The purpose of this experiment was to use elimination and confirmation tests for both cations and anions, which then allowed the unknown substance to be identified by using logic trees of known solutions. Some qualitative characteristics of chemicals such as the formation of a precipitate, the…

compounds would create a specific reaction. Whether or not a reaction would happen would indicate the presence of anions; for example, we took a pinch of sodium sulfate and added it to a test tube, added 1mL of hydrochloric acid, and then added barium chloride to the test tube. This reaction formed a white, milky precipitate, indicating sulfate ions' presence; see Table 2 of week 1 for results. Then we moved on to our cation test; this test involved a pH test, flame test, and more reaction…
