Question
Oxidation and Reduction:
Water pipes have been made from lead since the Roman times. Whilst the health effects of
ingesting lead are well known, having lead pipes isn’t necessarily a problem if the lead does
not enter the water supply.
In the following equation,
1. Provide the oxidation states for each of the elements in lead (II) hydroxide (Pb(OH)2).
(2 pts)
2. State which element is being oxidised and which element is being reduced. (2 pts)
2 Pb (s) + O2 (g) + 2 H2O (l) → 2 Pb(OH)2 (s)
Balancing Equations:
Phosphate ions are added to the water supply to react with lead ions in the pipes and prevent
them leaching into the water.
In the following, balanced equation, I have not provided the charges of the cation or the anion
(highlighted in red).
3. Identify the cation and its charge. (1 pt)
4. Identify the anion and its charge. (1 pt)
5. Name the product. (1 pt)
Pb (aq) + PO4 (aq) → Pb3(PO4)2
Ionic Compounds:
6. How do the phosphate ions help prevent lead getting into the water supply. (2 pts)
