Title: The Reaction between Iron Power & Copper (II) Sulfate which Produces Iron (II) Sulfate & Copper Metal when Placed on a Hot Plate Mixed with Distilled Water. – Lab #4

Purpose/Problem: To determine the percent yield of copper using the theoretical yield and the actual yield from the experiment.

Hypothesis: If this experiment is conducted correctly then it will be easy to be able to produce the correct actual yield and be able to figure out the percent yield.

Materials:
• Copper (II) sulfate pentahydrate, & CuSo₄ •5H₂O,12.5g
• Graduated Cylinder, 50 or 100mL
• Iron Powder, FE, 2.24 g
• Stirring Rod
• Distilled Water, approximately 100 mL
• Heating Apparatus
• Electronic Balance
• Weighing Paper
• Beaker, 100 mL
• Plastic Spoon
• 125 mL Erlenmeyer Flask
• Filter Paper

Procedures:
1. Gather all the materials.
2. Measure out 50 mL of water and pour it in beaker.
3. Use hot plate to heat the beaker water to 50°C.
4. Obtain 12.50 g of copper (II) sulfate and record the mass in a data table.
5. Add copper (II) sulfate and heat for 5-10 minutes/until the crystals have dissolved. Stir solution with stirring rod.
6. Stop heating when all crystals have dissolved.
7. Obtain 2.24g of iron powder and record the mass in data table.
8. While stirring, add the iron powder to the hot copper (II) sulfate solution. Allow solution to sit for 10 minutes.
9. Stir solution occasionally and record any observations.
10. After the 10 minutes, filter the copper product and collect the liquid in a flask.
11. Clean all the used materials and throw away any unwanted trash.
12. Then lastly, place the copper product in the designated place to dry.

Observation/Data:
Mass of Copper (II) Sulfate 12.50 g
Mas of Iron powder 2.24 g
Mass of filter paper .4 g
Mass of Filter paper and Copper 3.3 g
Mass of Copper Recovered 2.9g
Observations of Fe + CuSO₄ Copper (II) Sulfate turns from blue to green. Copper metal begins to form on the bottom.

Independent Variable: Heat from the hot plate
Dependent Variable: Iron powder & Copper (II) Sulfate
Controlled Variable: Distilled water

The mass of Copper (II) Sulfate was 12.50g and the mass of iron powder 2.24 g. The mass of filter

gy------------------------------------------------- Etymology [edit] The term stoichiometry is derived from the Greek words στοιχεῖον stoicheion "element" and μέτρον metron "measure". In patristic Greek, the word Stoichiometria was used by Nicephorus to refer to the number of line counts of the canonical New Testament and some of the Apocrypha. ------------------------------------------------- Definition [edit] Stoichiometry rests upon the very basic laws that help to understand it better, i.e., law…

Can the Charge of Iron be Calculated in a Single Replacement Reaction With Copper (II) Sulfate, and Can a Hydrate be Predicted From an Initial and Final Mass? Sometimes atoms have more or less electrons than they do protons. These atoms are known as ions, any atom or molecule that has an ionic charge. Some atoms or molecules have “common” ionic charges, or a number of electrons that is normal for them. An example of this is sulfate, or which has an ionic charge of 2-, which means it has 2 more…

the determination of the amount of copper in a sample. Using a two-step reaction sequence, copper(II) oxide will be synthesized from a weighed amount of copper(II) sulfate pentahydrate. Stoichiometry allows us to use the balanced equation to calculate the amounts of product and/or reactant involved in a reaction. Because the starting material will be a pure compound, it will be possible - to check the validity of the technique by comparing the amount of copper(II) oxide predicted theoretically to…

The data gathered and calculated in the experiment accurately portrayed the way the reactions would have taken place. The chloride analysis was a little bit off from other groups due to the fact that our AgCl was in clumps, creating less surface area, thus our product took longer to burn and may not have burned correctly compared to other groups; yet there are several experimental factors that could have caused us to have different results than other groups, i.e. different measurements for samples…

To measure the amount of gas produced in this reaction, the number of Hydrogen gas moles was determined using stoichiometry. The pressure exerted by the H2 gas was derived using Dalton’s Law of Partial Pressures: PH =Patm-PH O. The partial pressure of the Hydrogen gas is the pressure of the water subtracted from the atmospheric pressure. The actual molar volume was…

Who Is The Father of the Periodic Table? There has been some disagreement about who deserves credit for being the "father" of the periodic table, the German Lothar Meyer (pictured here) or the Russian Dmitri Mendeleev. Both chemists produced remarkably similar results at the same time working independently of one another. Meyer's 1864 textbook included a rather abbreviated version of a periodic table used to classify the elements. This consisted of about half of the known elements listed in order…
