We did a lab on Ions and Atoms. The purpose was basically to identify the properties of an ion and compare them to atoms.
These were the Materials
-copper(II) chloride (CuCl2)
-3 250-ml beakers
1. Read the Procedure, and create a table to record your observations.
2. Put on your safety goggles and apron.
3. Your tacher will supply you with a beaker that contains approximately 1.0g of copper(II) chloride. Observe and record the properties of this compound.
4. Add approximately 100mL of water & stir until the copper(II) chloride is completely dissolved. Observe & record the properties of the copper(II) chloride solution.
5. Cut a 3 x 3 cm square of aluminum foil. Observe & record the properties of the aluminum metal.
6. Crumple the foil square & place it in the copper(II) chloride solution. Immediately begin to watch for any changes to the solution or the square of aluminum. Record your observations.
7.Use the string rod to ensure that all the foil is submerged. Continue to add small scraps of foil until the blue-green colour disappears from the solution.
8. Set up the ring stand with the funnel & filter paper, as demonstrated by your teacher.
9. Swirl the solution gently, and then pour it into the funnel, pouring along the stirring rod as shown in Figure 1. Touch the stirring rod to the spout of the beaker so that the liquid flows down the rod into the filter cone.
10. When all the solution has been poured, add some water to wash out the remaining solids.
11.Allow the filter paper to dry as directed by your teacher. Pour any remaining solutions into the container designated by ur teacher. Rinse the beaker, stirring rod, & funnel.
12. Observe the solid on the filter paper. Record ur observations.
I'll list my observations and questions on a new post, If I post them on here then it would be very long. Please take your time to read through this, thank you very much:-)
