Combustable of Acetylene

I. Title: Combustion of Acetylene

II. Goal: To prepare acetylene and determine the ratio of the quantity of acetylene to the amount of oxygen to get complete combustable. III. Elements:

1000 cubic centimeters beaker

Tap water

5 large evaluation tubes

calcium supplements carbide (CaC2)

googles and apron

matches

IV. Procedure:

1) Fill up a a thousand mL beaker ¾ filled with tap water.

2) Obtain some large test tubes.

3) Fill the first evaluation tube totally full with tap water. Fill up the 2nd check tube 50% full, the next 25% complete, and the 4th test tube 7. 4% full. 4) Place a small piece of Calcium Carbide (CaC2) into the 1000 mL beaker. As it responds with the normal water, it will contact form acetylene gas (C­­2H2). Place thumb within the 1st check tube and invert that into the multitude of mL beaker. When it is under the surface of the water, remove your thumb and placement the test tube to capture the bubbles of C2H2. 5) When CaC2 stops reacting, cover your mouth of the evaluation tube and remove it through the 1000 mL beaker. Keep your thumb tightly covering the evaluation tube. 6) Have a lab spouse strike a match and remove your thumb. Quickly place the oral cavity of the evaluation tube. Record observations. 7) Repeat while using other several test tubes.

V. Benefits:

Test Pipe

Observations

100%

Effect occurred quickly and a lot of gas. Not much flame when match was put over the test tube. fifty percent

Reaction happened not as fast, more flame was made when ever match was put over the test tube. 25%

Reaction occurred slow, a big flame of fire was made when match was set over the check tube, and black chemicals were up. 17. 4%

Reaction happened even slower, not much of your flame while the one from 25% unfortunately he bigger than 50% and 100% (although other labs have turned out this to be wrong. )
