Copper Sulfate Pentahydrate Purpose: To verify the formula for copper (II) sulfate pentahydrate by measuring the amount of water decomposed from the hydrated species. MSDS: Copper sulfate pentahydrate- Harmful if swallowed. Causes skin irritation‚ causes serious eye irritation. Very toxic to aquatic life with long effects. If copper sulfate stays in the stomach‚ the victim becomes unconscious. The symptoms of poisoning include diarrhea‚ headache and injury to vital organs. Background: 1

Objective: The objective of this lab is to determine and analyze the many chemical qualities of copper ‚ by using many solutions that enable copper to undergo chemical changes that will take copper from a metal back to its original state. This is done using cooper‚ Concentrated HNO3‚ 6 M NaOH ‚ Bunsen burner‚ 6 M H2SO4‚ Mg ribbon‚ and two test tubes. The techniques used in this lab which is cleaning glassware‚ disposing of chemicals ‚ measuring mass ‚ centrifugation ‚ venting gases‚ and test tube

Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was

Marie Remy Lab 02/19/13 Purpose To explore the cycle of copper through many chemical reactions. What we are going to do is take a piece of copper metal put it through a series of reactions that change it¡¦s state of matter and chemical formula‚ but in the end‚ we will return it to it¡¦s normal solid state. Determine the percentage yield (quantitative). Define what happen at level of electron for oxidation/reduction‚ double replacement‚ neutralization and decomposition. There are five reactions

Gold Penny Lab Purpose: The purpose of this lab is to convert a regular penny into a “gold” penny. Background: Chemistry is a branch of physical science that studies the composition‚ properties and behavior of matter (www.acs.org). Sodium hydroxide is considered to be a strong base because it breaks up in water. When mixed with certain metals it produces potentially explosive hydrogen gas. Many alchemists believed that doing certain chemical reactions that they would be able

Whether its the superstions of “luck” or just another penny to add into their collection. Only traditions explain our stubborn attachment to our pennies. However‚ pennies should not be abolished‚ they are beneficial to us in every days life. For example‚ people who have thousands of pennies saved up from over the years

April 10‚ 2013 The Penny The use of pennies is steadily declining. Most people don’t even keep track of the amount of coins they have‚ so it’s more than likely that they’ll think it’s useless‚ and dispose of it. People would throw away the pennies they have‚ without a second glance. Bit if we all save up our loose change‚ there’s a chance we’d be able to save up to hundreds‚ or possibly even millions of pennies. Pennies are valuable to some people‚ for example‚ coin manufactures (Source

In order to find the formula of the copper chloride hydrate‚ we had to separate the compound to find the mass of water and copper. To begin this process‚ we evaporated the water and created an anhydrous compound‚ meaning we were left with only CuxCly. By calculating the weight of both the anhydrous and the hydrated compounds‚ we could conclude that the difference in the weights was the weight of the H2O. From this we were able to calculate the percent composition of CuxCly and H2O (see Calculations:
