The Effect of Chemicals on Fire
The Effect of Chemicals on Fire In this lab we got to see the effect of chemicals on fire. We got to. See the flames change to different colors. The size of the colorful flame depended on how the Bunsen burner was turned on. I was sick when we were supposed to have the lab read, but I got it read the next day before class. During the lab I made sure to have the correct attired on: my goggles and apron. Ow ill go ahead and tell you five good safety precaution tips. One, never leave a lit burner unattended. Two, never fools rounding n the lab. Three, dispose of all chemical waste properly. Four, report any accidents or injuries. And last but not least, five, never return unused chemicals to their original containers. To start out the lab you will need to make sure that you have all the correct materials, such as: a Bunsen burner, a striker, solutions of known and unknown chemicals, and wooden sticks. First, you will prepare the wooden splint for the flam test as directed by your instructor. Second, you will light the Bunsen burner at your lab table. Next, you will dip your wooden splint into a known solution. After that, you will record the name of the solution exactly as written along with the color of flame you observed in the chart results. Following, you will dip the wooden splint in another known solution and observe the through the spectroscope. Then you will move to the next lab station where you will find a new known solution. You will repeat the above steps with each solution. When you test the solution containing a sodium compound, observe and record the color of the flame. Test it again by observing the flame through two pieces of cobalt blue glass held together. Record the flame color with the cobalt blue glass on a separate line. You will observe the solution of sodium chloride mixed with potassium chloride without the cobalt blue glass and then again with the cobalt blue glass. Record the color of the flame seen not two separate lines.
