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

Copper to Silver to Gold—A Comparison of Physical and Chemical Changes (Adapted from Abra-Ka-Dabra by C. M. Bires.) Introduction Hundreds of years ago‚ noblemen and women would pay large sums of money to alchemists. These early chemists were similar to modern-day illusionists in that they used a little science‚ a few tricks‚ and some acting to convince their clients that they had the ability to transform base metals into pure gold. Although these alchemists were eventually revealed as charlatans

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:

Lab #18 Stoichiometry In this lab‚ we reacted aluminum foil with a copper chloride solution‚ and determined the amount of metal that should be produced‚ given the amount of aluminum used. First‚ we obtained a piece of aluminum with a mass of 0.809 g‚ and reacted it with 100 mL of Copper II Chloride‚ after heating the solution. Then‚ we filtered out the copper separated in the reaction using filter paper‚ massing 0.751 g. Once all the solution was filtered‚ we massed the new filter paper filled with
