Next Experiment Procedure

1. Pour 25 mL of the solution into a beaker using a graduated cylinder, then pour a small amout into a test tube labeled "Ca2+ ion".

2. Put a wooden splint into the test tube and set it aside.

3. Pour 25 mL of lithium carbonate solution into the second beaker, and pour a small amount into another test tube labeled "Li+ ion".

4. Put a wooden splint into the second test tube and set it aside.

5. Pour the contents of the beaker containing lithium carbonate into the beaker containing calcium chloride.

6. Pour the contents of the beaker into the filter paper.

7. After filtering, pour the remaining liquid substance into a beaker labeled "Unkwon ion".

8. Put a wooden splint into the "unknown ion" test tube and set it aside.

9. Set up a bison burner to between a safety flame and a roaring flame.

10. Take the wooden splint from the test tube labeled "Ca2+" and hold it over the bunson burner. Take note of the flame colour.

11. Take the wooden splint from the test tube labeled "Li+" and hold it over the bunson burner. Take note of the flame colour.

12. Using the crucible tongs, scoop some white stuff left in the filter and hold it over the buson burner. Observe the colour and dicide wether it's Ca2+ or Li+.

13. Take the wooden splint from the test tube labeled "Unknown ion" and hold it over the bunson burner. Observe the colour and dicide wether it's Ca2+ or Li+.
