Interpretation : It must be explained why the statue's copper (II) carbonate coating has distinct characteristics from the bronze underneath. These properties are a result of the type of bonding present that is to be explained.
Concept Introduction : Bronze is an alloy that is composed of copper and tin.
Answer to Problem 94A
The bronze is reactive with the atmosphere whereas the copper (II) carbonate is non-reactive and stable.
Explanation of Solution
The statue is made of bronze alloy. The statue gets reacted with the atmosphere.
Over time, the copper present in bronze reacts with oxygen, carbon dioxide, and water and forms copper (II) carbonate.
The color of copper (II) carbonate is blue-green powder.
The copper (II) carbonate film is stable and it does not further react.
