In this experiment, we used a bunsen burner to ignite different chemical solutions that had been soaking onto a wooden splint. The ignition of these solutions created many different colored flames which we observed.
For the last part of the lab, we identified the unknown substances based off of the data we had collected about the known substances. For unknown solution one we identified it as Strontium Chloride. When we burned the substance, it gave off very red light. We knew that it was either SrCl2 or LiCl because both of those gave off red light; however, LiCl gave off orange light in addition to red light and the unknown substance gave off solely red light, which allowed us to determine the true identity of the substance. Unknown substance two gave off a purple light. The only solution that gave off a purple light in our experiment was Potassium Chloride, so we knew that the unknown substance had to be Potassium Chloride, or KCl.
