It can be corrosive to skin. Also be cautious of the fire with the Bunsen burner. It can catch hair on fire and can also provide a burning hazard. Conclusion: In this reaction we were able to successfully complete the hypothesis. We created the CaCl2 with a 104% yield, which was very good. We also were able to see the water leaving as steam as shown in the equation. This was very interesting to observe because in many other equations and experiments, you are not able to watch the actual reaction take place....
