Why hydrogen squeaky pop




















In general:. For example:. Zinc and iron also react with hydrochloric acid. Magnesium, zinc and iron also react with sulfuric acid. The products are a salt in this case a sulfate and hydrogen. Name the two products of the reaction of zinc with hydrochloric acid. The products are zinc chloride and hydrogen. Do the same experiment but warm the acid a bit. Discuss the results with your students. Meredith Juncker, PhD. The products of the squeaky pop test are soluble magnesium chloride MgCl2 aq and hydrogen gas H2 g.

Not Helpful 6 Helpful 7. Hydrogen is not toxic, but in its pure form is a chemical asphyxiant. Avoid inhaling it. Not Helpful 2 Helpful 5. No, as long as the strip is magnesium, it should work fine for this experiment. Not Helpful 4 Helpful Lin Ying Tey. The only difference would be in the salt produced. If you use hydrochloric acid, magnesium chloride would be formed.

If you use sulphuric acid, magnesium sulphate would be produced. Either way, hydrogen gas would still evolve. Not Helpful 3 Helpful 5. The Fact-O-Logy. It concludes that the reaction has a product of hydrogen, which is a flammable gas. And we can use this property of hydrogen to test for it. Not Helpful 0 Helpful 4. What is a balanced equation to the reaction of the hydrochloric acid with magnesium and the lit match? Not Helpful 1 Helpful 3.

Take care not to get acid on your skin or clothes. Helpful 0 Not Helpful 0. If you are a child or teenager, make sure to do this in the presence of an adult. Always wear eye protection as hydrochloric acid releases acidic mist.

The total volume of hydrogen that could be produced using the given quantities zinc is in excess is just over cm 3. The rate at which hydrogen is produced will depend on the surface area of the zinc granules. Avoid large lumps and carry out a test run before the class to check that the volume and rate of hydrogen production is sufficient to fill three test tubes to a marked volume once the air has been flushed out of the apparatus.

The copper sulfate reacts with the zinc, forming a deposit of copper metal on the zinc. This acts as catalyst, speeding up the production of hydrogen. A single dropping bottle of the solution should be provided at a central point.

Show Fullscreen Source: Royal Society of Chemistry The equipment required for generating and collecting hydrogen gas using zinc and hydrochloric acid. Important Before proceeding to the next step, remove all the hydrogen generating apparatus to a safe place. Additional information This is a resource from the Practical Chemistry project , developed by the Nuffield Foundation and the Royal Society of Chemistry. Buttonwood Buttonwood The only nitpick I have is the first sentence of the second paragraph about the expansion due to the phase change.

But the rest of that paragraph hits it; the rapid thermal expansion in a confined area. Anyway, nice answer. Had I written the chemical equation first If you want to try a demo on this. Find a thin tin used for say granulated coffee, make a 2mm hole in lid and one in base for a rubber tube. Place on retort stand, fill with hydrogen from cylinder until you are sure its full, a minute or so, then remove tube close cylinder and get cylinder well away. Light hydrogen at hole in lid. Will burn then go out as it explodes.

Lid is light , flies off, no damage. Have done this is lectures several times. Great fun. Sign up or log in Sign up using Google.
