Making Carbon Dioxide Gas Experiment

If you ever wondered how to create some carbon dioxide gas by your own without those complex and hectic scientific processes. Here is the easier way to make carbon dioxide gas.

Aim: To test for carbon dioxide gas.

Equipment

  • Limewater/Calcium Hydroxide (CaOH)
  • Calcium Carbonate (CaCO3)
  • Hydrochloric acid (HCI)
  • safety glasses
  • stopper/cork
  • one-arm test tube
  • test tube rack
  • medium sized beaker (150 ml)
  • small sized beaker (50ml)
  • rubber tube

Method

  1. Setup the equipment as shown in the diagram.
  2. Pour some limewater into the beaker
  3. A small amount of calcium carbonate is added into the one-arm test tube
  4. Pour some hydrochloric acid to the one-arm test tube
  5. Quickly put the stopper on top of the one arm-test tube
  6. Make sure the rubber tube is in the beaker which contains the limewater
  7. Record the observations

Diagram: (Again, sorry for the unclear drawing.)

Results:

  • When calcium carbonate was added to the hydrochloric acid, the solution fizzed, showing that there is gas produced. When the gas had reached the limewater, it had started to appear milky.
  • To make sure the experiment was safe; you should wear safety glasses and be careful in handling the acids which might cause some irritation

Conclusion

Carbon dioxide gas was tested by adding calcium carbonate and hydrochloric acid together. This had resulted for the limewater to emerge milky.

    where cAn you find or buy carbon hydroxide or limewater?

    You could simply buy it in some store that specialises those kinds of things.

    how do i make carbon dioxide not how do i test for it

    When you mix baking soda and vinegar it gives of carbon dioxide gas. Do this in a test tube and put a balloon (or something) over it to catch the co2.

    TIP: Inhailing co2 will give you an adrenaline rush.

    what could be some possible variables for this lab? all i can think of is the length of the rubber tube, but all that affects is how quickly the CO2 reaches the CaOH solution. so it is fairly insignificant.
    other than that, are there even any other variables?
    thank you !

    @arooobine:

    Inhaling concentrations of CO2 may lead to drowziness, nausea and eventual unconciousness within a few minutes to an hour. It is dangerous and should not be attempted.

    Hello, I’m doing this lab report on this experiment we did in class and i lost some of the info i needed to complete it. i just wanted to know what happend when you put a lighted splint in a test tube with co2 in it. and also what happens when you put a glowing splint inside. thanks

    the chemical equation would be: CaCO3 + 2HCl = CO2 + H2O + CaCl2

    can i have a word equation for heat and copper carbonate makes carbon dioxide? i don’t understand if it is heat or oxygen you put in it.

    Please balance equation

    CaCO3 + 2HCl = CO2 + H2O + CaCl2
