Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6

may affected the mass of the copper was recovered and also the percentage of yield. According to the law of conservation of matter‚ the mass of the copper will not change even though there are many chemical reactions happened which also mean that the mass of copper contained in solutions or precipitates remain the same as the copper in the beginning. And it is necessary to synthesize the various copper compounds in order to recover metal because the amount of copper might be left due to some errors

DETERMINATION OF COPPER BY COMPLEXATION‚ SOLVENT-EXTRACTION AND SPECTROPHOTOMETRY ABSTRACT To determine the concentration of copper in an unknown solution by using copper complexation‚ solvent extraction and spectrophotometry. Standards are used to create a calibration curve and the unknown concentration of copper is then calculated by using the linear equation from the calibration curve. The concentration of copper in the unknown solution 201 was found to be 12.57± 0.25 μg/mL. INTRODUCTION Copper is an

Copper Chloride Lab Report Procedure Part A: 1. Pick up the container of copper chloride dehydrate‚ and observe material. Describe crystals in detail‚ and write down all of the observations. Part B: 1. Take a 100 ml beaker and fill ¼ of it with water. Use a spatula to add some copper chloride dehydrate to the beaker filled with water. Record the observations. Be sure to observe the water and the copper chloride dehydrate. 2. Stir the contents in the beaker with

Quantitative Analysis of a Soluble Sulfate Steven English Lab Instructor: Dr. Campo Date: Tuesday‚ February 5th 2013 Pre-Lab Questions A. Adding the acid to the sodium sulfate solution results in an increase in the solubility of any free anions present in the sample. This will happen because the present anions will bind with the hydrogen cations present in the acid. B. The sodium sulfate is boiled because experiments have shown that barium sulfate is 50 times more soluble at 100°C

This laboratory was performed to find the temperature change‚ heat of reaction‚ and enthalpy change for neutralization reactions. The temperature change was found by subtracting the initial temperature from the final temperature obtained. Heat of reaction is negative heat of solution. Heat of solution was found by using the formula qsolution = mCsΔT (m= mass; Cs= 4.184 J/g°C; and ΔT = change in temperature). The enthalpy change was found by dividing the heat of reaction by the number of moles of H2O

Determining the Percent Copper and Zinc in Pennies from Density Lab Report Procedure: For pre-1982 pennies- Mass 10 pennies‚ record data. Fill a 100mL graduated cylinder to 40mL or enough to fully submerge the pennies with water‚ record the volume in data table. Carefully place the pennies into the graduated cylinder‚ record the final volume of the water in data table. To find the volume of the pennies‚ subtract the final volume from the initial‚ record the data. Repeat this procedure twice more
