Bunsen Burner Lab
I. Objectives A. Able to use Bunsen Burner B. Show to handle liquids and solids in lab. C. Basic safety and Electric balance. D. To show knowledge of being able to find volume of a liquid.
II. Equipment.
A. Bunsen Burner
B. Rubber Hose
C. Striker
D. Electric Balance
E. Crucible Tongs
F. Piece of paper
G. Gas and Knob
H. Copper Wire
I. 2.75g of Sugar
J. Test Tube
K. Graduated Cylinder
L. Water
III. Procedure
• Put on Safety Goggles.
• Bunsen Burner Lab o Attach Rubber hose to gas line o Turn Gold knob counter clockwise to allow gas o Open ports for air. o Turn gas on o Light with striker the Bunsen Burner o Adjust gas to quiet steady flame. o Using crucible tongs hold piece of copper for five seconds over Bunsen Burner in different parts of the flame o Turn off Bunsen Burner using gas knob
• Sugar Lab o Zero out Electric Scale. o Put 2.75g of Sugar on Paper o Fold Tray in half and pour sugar in to small test tube. o Rinse and discard materials
• Water Lab o Make Procedure o 3 different amounts of water in Graduated Cylinders and record. o Measure mass on scale to find weight or mass of water o Divide weight by volume
IV. Analysis
• Observations o For Sugar Lab I observed the weight of the Sugar and observed it transfer to the shape of the test tube when put in the test tube. o During Copper Lab I observed copper change from copper brown tint, to a gray silver tint. o Water lab I observed the comparison between volume and mass.
Mass (g) Volume (mL) Density (g/mL)
3.9 4.9 0.79591837
33.48 34.81 0.96179259
49.58 50.5 0.98178218
• Table o • Graph
Conclusion
• This lab has shown that the data was collected mostly responsible through consistency of the Water lab.
• In theory even when you change the amount of liquid the density ratio of water should not change because you are changing the variables only.
• This shows almost accuracy because we got densities very similar on our three different
