You have a sample that contains sucrose, sand and copper sulfate. Would you be able to separate these three components from each other, if so how?
The components of the given sample containing sucrose, sand and copper sulfate can be separated as follows.
1. Add water to the sample. Sucrose and copper sulfate are soluble and hence will completely dissolve in water. The sand will remain in the solution. Separate the sand by filtration. Pour off the solution and wash the remaining sand with some more water.
2. Now, add ethanol to the solution containing sucrose and copper sulfate. The copper sulfate will precipitate from the solution as it is insoluble in ethanol and sucrose will remain dissolved in the solution. Filter the solution to separate the copper sulfate.
3. Then, evaporate the filtrate to obtain sucrose.

You have a mixture of sucrose (C12H22O11) and sand (SiO2) in a beaker. What type of mixture is this? Explain how you know. What process(es) would be best to separate this mixture? Describe the process.
A student obtains an unknown mixture of copper sulfate and sand from the Stockroom Window, and carries out the procedure for Experiment 2 carefully as written. The student obtains the following data: Part A Mass of unknown sample and test tube: 9.1589 g Mass of test tube: 7.8965 g Part B Mass of Filter Paper: 0.6127 g Mass of Watch Glass: 6.9548 g Combined Mass of Watch Glass, Filter Paper, and Sand: 7.879 g Calculate the Mass % of Sand...
A tube containing 8.00 mL of 0.250 M copper (II) sulfate contains 2.00 x 10^-3 mole of copper (II) sulfate. how many grams of solid copper (II) sulfate would this be equivalent to? using dimensional analysis
You have a 5.0 M copper sulfate stock solution and a 2 M NaCl stock solution. You wish to prepare a solution with a final concentration of 0.25 M copper sulfate and 0.25 M NaCl containing 330 mL of water as a solvent. How many milliliters of the NaCl stock solution would the solution contain?
S. (10 points) In the laboratory, you have available; solid crystals of copper (II) sulfate pentahydrate, lab balances, plenty of distilled water and access to all standard glassware. Explain with as much detail as you can, how you would prepare exactly 200.0 mL. of a 0.0600 M aqueous solution of copper (II) sulfate pentahydrate (CuSO 5H2O) 0.0600M ML 200.ML 11
You make 1,000 L of an aqueous solution that contains 35.0 g of sucrose (C12H22011). (a) What is the molarity of sucrose in this solution? (b) How many liters of water would you have to add to this solution to reduce the molarity you calculated in part (a) by a factor of two?
2. Assume you start with a 2.00 g sample of copper (II) nitrate. a. How many moles of copper (II) nitrate do you start with? b. Your sample will undergo multiple steps, each of which has the potential for loss of product. Assuming a percent yield of only 65.0 %, how many moles of copper (II) sulfate would you expect to produce? c. If the product is now dissolved in water inside of a 50-mL volumetric flask (as in the...
