1. Fe → Fe2+ + 2 e. The following redox reaction also occurs in the presence of water and is crucial to the formation of rust: 4 Fe2+ + O2 → 4 Fe3+ + 2 O. ... From the above equations, it is also seen that the corrosion products are dictated by the availability of water and oxygen.
2. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur.
3. Ionization energy is the amount of energy required to remove an electron from an isolated atom or molecule.
4. When dilute sulphuric acid poured on a copper plate, the metal does not react with sulphuric acid. But when concentrated sulphuric acid is poured over the copper plate, it librates hydrogen gas.
5. Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.
