My Unknown, Flame Test, And Anions

CONCLUSION
After many class lab days, I concluded my unknown was Calcium Carbonate due to results from the Flame Test and Anion I Test. Throughout our lab days, my friends would help me determine various odors and colors of the substances which allowed me to confirm my answer. Also, I looked select test results up on the internet to see if they matched my observations.
On our first lab day, I received my bottle and noticed a white precipitate in the bottom therefore, my unknown was insoluble. I started my testing with the Flame Test and did not evaporate my unknown. I just used the liquid solution to test for the flash color. Just to ensure my results were clear, I decided to evaporate my unknown on the second lab day to test for my unknown with a dry sample. After my unknown was evaporated, I could use my dry sample for the first three tests, the Flame Test, Bead Test, and Cobalt Nitrate test. As I moved the chromel wire with my dry unknown through the flame for the Flame Test, the results were indicative of Calcium. The dry sample of my unknown had a dark orange flash color and the liquid solution was bright orange. To ensure my results I used the Group V Cation Test to test for Calcium as well. The solution stayed a cloudy white matching the results for Calcium. Through both the Flame Test and the Group V Cation Test, I was able to
If in need to extinguish a fire containing Calcium Carbonate, one must wear an NIOSH/MSHA, National Institute for Occupational Safety and Health/Mine Safety and Health Administration, approved, self-contained breathing apparatus and full protective clothing. Also, if a spill or leak occurs, vacuum cleaning systems are recommended and soap and water should be used to clean spill areas. To store calcium carbonate, one should store it in a cool area and keep it away from acids because this compound will react to produce carbon
