Diffrent types of gas experiments

Testing for Hydrogen Gas

Metal + Acid = metal salt + hydrogen

Magnesium + Sulfuric Acid = magnesium sulfate + hydrogen 

Equipment: A test tube, a boiling tube, bunsen burner, wooden splint, a bottle of acid, a piece of metal, safety glasses.

Method:

• Light a bunsen burner

• Add your sample of metal to your test tube add sml of acid

• carefully invert the boiling tube above the test tube containing the metal and acid ( as shown in the diagram below)

• Hold the test tube together for a few minutes allowing time for the inverted boiling tube fill with gas

• When you think the tube is full, your lab partner should light a wooden splint.

• Carefully , but quickly, titl the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube

Conclusion :When we light the wooden splint with fire and put in the mouth of the tube it made a sound a popping sound

Metal + acid = Metal Salt + Hydrogen (Poptest)

Metal + Oxygen = Metal Oxide

Metal Oxide + Hydrogen Peroxide = Metal Hydroxide + Oxygen ( Glowing Splint)

Making a Metal Oxide

Aim: To make a metal oxide and observe the different in properties of the product compared to the reactants

Equipment:A piece of magnesium, Bunsen burner, safety glasses, metal scissor tog

Method :

• Light the bunsen burner

• hold the piece of magnesium in the scissor tongs. Ensure you are holding onto the very tip of the magnesium.

• place the other end of the magnesium into the bunsen flame(at the top of the blue flame)

• when the magnesium begins to burn, do not look directly at it, as the light emitted can permanently damage your eyes

Conclusion : When we light up the magnesium we had to look away because the light was to bright your eyes might get infected 

Testing For Carbon Dioxide Gas 

Aim: To show that carbon dioxide gas is produced  when a metal carbonate reacts with acid

Equipment: Two boiling tubes, delivery tube and bung, Bunsen burner, test tube rack,wooden splint, a bottle of acid, small amount of metal carbonate, test tube tongs safety glasses.

Method: 

• Light your bunsen burner
•  Add a pea - sized amount of the metal carbonate into one of the boiling tubes
• Place this boiling tube into a test tube rack. Ensure you have the bung and delivery tube ready
• Add 5 ml of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the boiling tube
• Holding the other boiling tube with your tongs, capture the gas produced as shown in the diagram below
• When you think the tube is full, your lab partner should light a wooden splint
• Carefully remove the boiling tube for under the delivery tube taking care to keep it facing upright
• Insert the burning splint into the mouth of the test tube

Conclusion :

As soon as we put the half of the tube the the lime juice it bubbled up and the lime juice kinda went cloudy.
