9. H 2 O HOH + e - water electron Positively charged water molecule Radiation reacts with water to produce an electron and a positively charged water molecule.
10. H 2 O HOH + e - + H 2 O HOH - water negatively charged water molecule electron water Positively charged water molecule The electron reacts with another water molecule to produce a negatively charged water molecule
11. H 2 O HOH + H + OH * e - + H 2 O HOH - water negatively charged water molecule Hydrogen ion Hydroxyl radical electron water Positively charged water molecule The positively charged water molecule dissociates into a hydrogen ion and a hydroxyl radical.
12. H 2 O HOH + H + OH * H * OH - e - + H 2 O HOH - water negatively charged water molecule Hydrogen ion Hydroxyl radical electron water Positively charged water molecule hydrogen radical Hydroxyl ion The negatively charged water molecule dissociates into a hydrogen radical and a hydroxyl ion.
13.
14. HOH + + e - H 2 O The positively charged water molecule and the electron recombine to form water. H 2 O HOH + H + OH * H * OH - e - + H 2 O HOH -
15. H + + OH - H 2 O The ions combine to form water. H 2 O HOH + H + OH * H * OH - e - + H 2 O HOH -
16. H * + OH * H 2 O The radicals combine to form water. H 2 O HOH + H + OH * H * OH - e - + H 2 O HOH -
17. H 2 O HOH + H + OH * H * OH - e - + H 2 O HOH - OH* OH* + OH* H 2 O 2 The hydroxyl radical reacts with another hydroxyl radical to form hydrogen peroxide.
