2. 1. Corrosion of Iron Metal
The rusting prosses in iron can be written in the following equation. 4
Fe(s) + O2(aq) + H2O(l) → Fe2O3.3H2O(l) 3 6 2 -2 +3
OXIDATION
REDUCTION

3. 2. Clothes Bleaching 6 NaOCl + H2O → NaCl + NaOH+ O2+ Cl2 2 2 4 2 4 +1
When NaOCl dissolved, it is dissociated into ions, Na+ and OCl-, OCl- ion is reduced into chlorine ion and hydroxide ion 6
NaOCl + H2O → NaCl + NaOH+ O2+ Cl2 2 2 4 2 4 +1 -1

4. 3. The Accumulator Electrocuting
Pb + PbO2 + H2SO PbSO4 + H2O
