Redox Reactions Around Us
Reaksi Redoks di Sekitar Kita
1. Corrosion of Iron Metal
The rusting prosses in iron can be written in the following equation.
Fe(s) + O2(aq) + H2O(l) → Fe2O3.3H2O(l)4 3 6 20 0 +3 -2

2. Clothes Bleaching
When NaOCl dissolved, it is dissociated into ions, Na+ and OCl-, OCl- ion is reduced into chlorine ion and hydroxide ion
NaOCl + H2O → NaCl + NaOH+ O2+ Cl226 42 2+1 -1 0
