Stoichiometry Lab Report
930 Words | 4 PagesThe process of filtration can be used seeing as the copper particles will be caught by the filter because they are too large to pass through it, while the aluminum chloride particles are small enough to pass through the filter. In order to filter the products, one needs to obtain a funnel, filter paper, and a clean
Double Displacement Reaction Lab Report
252 Words | 2 PagesIn cycle one, the double displacement reaction, Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) occurred, the result of the reaction was that the reaction mixture began to bubble with the copper filling dissolving and a vapor like substance leaving the reaction. Furthermore, when water was added, the color change, from brown to a blue color pigment. Then in Cycle two, another double displacement reaction occurred, Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq), which resulted in the reaction becoming cloudy and a darker shade of blue. Following cycle two, a decomposition reaction occurred as the result of heat being administered to the mixture, thus the following reaction occurred in cycle three, Cu(OH)2(s) → CuO(s) + H2O(l). As a
Copper Cycle Synthesis
578 Words | 3 PagesAl(s) wire was placed in the solution from the last step and 5 drops of HCl along with a stir bar was added to the beaker and this was stirred on the hot plate. Cu(s) precipitate formed on the wire and the solution turned from clear to cloudy until it eventually become a brownish red color. When the reaction was complete the Al(s) wire was scraped with the stirring rod to get off any residual Copper product. All of the reactions except for reaction 3 were exothermic. This is because each reaction gave

Hrm 531 Week 6 Material Safety Check
773 Words | 4 PagesQuestion 1. The first step I am going to take as the new safety manager of Dosit to bring them up to compliance with the Hazard Communication Standard would be to conduct an extensive chemical inventory check. The current chemical inventory list of 780 chemicals is over two years old and is outdated by a year. Periodic chemical inventory audits should be done at least once a year(David Fender,2012).

1027 Words | 5 PagesNext, a 100 mL graduated cylinder was used to measure 60 mL of distilled water. The water was added to the compound and stirred with a glass-stirring rod until dissolved. Next, The flame test required the solution made during the solubility test. The experiment needed a metal wire that was dipped into the solution
Potassium Chloride Lab Report
976 Words | 4 PagesDiscussion The ideal Van't Hoff factor for potassium chloride is 2, because the compound dissociates into its ions, K+ and Cl-. The greater the Van't Hoff factor means the more a compound lowers the freezing point temperature of the solvent it dissolves in. For a liquid to freeze it must form a lattice, a three-dimensional arrangement of particles that make up a crystalline solid, and the presence of solute particles interferes with the ability of the solvent particles to form a lattice. To compensate the system must be brought to an even lower temperature to freeze, and the more particles that are present within the solvent, the larger that freezing point depression becomes.3

800 Words | 4 PagesBalanced Chemical Equation: Cu(s) + 4HNO3(aq) —> Cu(NO3)2 (aq) + 2NO2 (g) + 2H2O (l) Reaction 2: when sodium hydroxide (NaOH) is added to copper (II) nitrate (Cu(NO3)2), a double displacement reaction will occur. Copper and sodium will displace each other to create copper (II) hydroxide and sodium nitrate. Balanced Chemical Equation: Cu(NO3)2 (aq) + 2NaOH (aq) —> CuOH2 (s) + 2NaNO3 (aq) Reaction 3: When copper (II) hydroxide is heated, a decomposition reaction will occur. The reaction will decompose forming two compounds, Copper (II) oxide, and water. Balanced Chemical Equation: Cu(OH)2 (s) + Heat —> CuO (s)
Copper Recovery Lab Report
471 Words | 2 PagesThe percent recovery of the copper was calculated using the equation, percent recovery = (the mass of the copper recovered after all the chemical reactions/the initial mass of the copper) x 100. The amount of copper that was recovered was 0.32 grams and the initial mass of the copper was 0.46 grams. Using the equation, (0.32 grams/0.46 grams) x 100 equaled 69.56%. The amount of copper recovered was slightly over two-thirds of the initial amount.
Nitration Of Methyl Benzoate Lab Report
487 Words | 2 PagesFor this lab we performed an electrophilic aromatic substitution through the nitration of methyl benzoate. Aromatic compounds can and do react with electrophiles under vigorous reaction conditions and in a presence of a catalyst. The stability of aromatic compounds is a result of resonance. Aromatic compounds only react with powerful electrophilic reagents and elevated temperatures because aromatic electrons are less reactive in addition reactions as formation of a carbocation intermediate entails loss of resonance stabilization. The nitration of methyl benzoate to synthesize methyl m-nitrobenzoate is an example of an electrophilic aromatic substitution because a nitro group is substituted for a proton on the aromatic ring.
Empirical Formula Of Copper Chloride Lab Report
729 Words | 3 PagesAs soon as the wire was submerged into the solution, the aluminum atoms and the copper (II) ions underwent a reduction-oxidation (redox) reaction, meaning aluminum was oxidized and donated its electrons to the copper ions, which were reduced. As a result, solid copper began to form on the surface of the aluminum wire, giving the wire a brown-orange color that resembled rust. The wire had to be regularly shaken in order to remove the solid copper particles and thereby expose more of the aluminum wire to react with the surrounding solution. As the reaction progressed, the liquid copper chloride solution slowly began to lose its color and turn clear. This was a chemical reaction, as seen by the bubbles formed with the wire was added, meaning gas was released when aluminum was oxidized and copper was reduced, but it also gave rise to physical changes, such as the change in color of the solution from blue-green to rusty orange to clear.
Properties Of Substances Lab Report
1038 Words | 5 PagesProperties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has
