Bunsen Burner In class on Monday. We learn how to use a Bunsen burner. We had to tell what was the hottest and coolest part of the flame. When we finish that.
We had to take a wire and go up and down in the flame to see what was the hottest part of the flame. After we did that, we had to take a evaporating dish, and put it into the flame and see what would be collected on the dish. To hook the Bunsen burner up. We had to connect the burner to a gas jet with the rubber hose that was hook to the burner. Then we had to make sure that the needle value was rotating barrel was closed, so no gas or air was not going through the burner.
To light the burner we had to open the needle value so the gas can flow through the burner. Then take a lighted match over the side to light it. Don t allow any air when you are lighting the burner. When it is lit you will see a yellow flame. Then you would take the evaporating dish and put it in the flame for a few minutes.
To see what would be collected on the dish. after you do that. Then you turn the barrel until you can t see the yellow flame anymore. Then put the dish in the hottest part of the flame and see what happens. After you do that. You would cut off the burner by closing the needle value and closing the barrel.
Then you would cut off the gas. In the conclusion the hottest part of the flame was the top part of the flame, and the coolest part of the flame was the blue cone in the middle. Soot was on the bottom of the dish the first time. When you put the dish back in the hottest part of the flame. It had cleaned the bottom of the dish. That is how you use a Bunsen burner.
