  1. Hydrogen Material: - Production of hydrogen properties of hydrogen Why is hydrogen unique Test for hydrogen Uses of hydrogen

  2. Production of hydrogen As the reaction between a metal and acid produces hydrogen, we can place this reaction in a flask that is connected to a delivery tube, that will allow hydrogen to pass through it ending up in a water trough, hydrogen will try to escape by bubbling up into the glass jar

  3. Properties of hydrogen • Colorless: - can’t be see • Odorless: - has no small • Tasteless: - doesn’t have a taste • Gas: - found in gas state, not liquid, or solid • Lightest gas: - least density, lighter then air • Explosive: - H2 + O2 H2O + energy reactants combine causing an explosion

  4. Why is hydrogen unique? • Hydrogen is knows as a very unique element as: - • It is a non-metal in group(I) - Usually elements in group(I) are metals 2) It tends to form more than one ion - H1+ is non as a proton (stable) - H1- is known as a hydride (unstable)

  5. Test for hydrogen • A boy forgets to label contents of 2 tubes, but he remembers that one of them has hydrogen, and the other has carbon dioxide He asks his teacher, “how do I test for hydrogen?”, and the teacher answers him… Test: - expose the gas to a lighted splint (in the presence of oxygen) Result: - it’ll explode with a squeaky “pop sound” The equation for the rxn is as follows: - H2 + O2 H2O + energy • The problem is that their both • Odorless • Colorless • Tasteless • Gas

  6. Uses of hydrogen • Hydrogen is a very useful gas • It is used as a fuel • It makes ammonia, NH4 (a soil fertilizer) - 3H2 + N2 2NH4 3) It is used to make plastic (PV) 4) It also turns liquid vegetable oils into margarine
