Question: Consider following reaction: 2Cu + H2O + CO2 + O2 ? Cu(OH)2 + CuCO3 Would the corrosion product be a good corrosion barrier? Justifyyour answer

Consider following reaction:

2Cu + H2O + CO2 + O2 ? Cu(OH)2 + CuCO3

Would the corrosion product be a good corrosion barrier? Justifyyour answer with the Pilling-Bedworth ratio.

Start from the beginning of the derivation and divide the volumeof the product by the volume of the reacted metal. Hint: in theabove reaction, consider 2 mols of Cu reacted and go fromthere.
