Purpose: Over the spring 2024 semester you have, I hope, developed an appreciation of
the fact that chemistry and chemical processes affects every aspect of your life. The article
associated with these review questions describes a situation in recent American history
where knowledge of chemistry, especially redox chemistry, acid-base chemistry and
chemical equilibria, were essential to understanding and stopping a developing public
health crisis.
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 (→ 2 Pb(OH)2 (s)
pb is reducing and o2 ia oxidizing
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)
