Paper 3: Rusting of Iron!!!

 

1. Problem statement: How does the types of metals will affect the rusting of iron?
2. Hypothesis: The more electropositive metal will prevent the rusting of iron, while the less electropositive metal will rusting the iron.
3. Memorise the material (types of metals and solution) and apparatus (test tube, test tube holder).
4. The step of experiment: Clean --> Coil --> Pour --> Few days --> Record observation.
