Expected Changes
- When a clean iron nail is placed in a solution of copper sulfate, you can expect the following changes:
- The solution will gradually change color from blue (the color of copper sulfate) to a lighter hue.
- The iron nail will show signs of rusting and may become coated with a reddish-brown substance.
Chemical Nature of Changes
- Yes, these changes are of a chemical nature.
- A chemical reaction occurs between the iron and the copper sulfate solution, leading to the formation of new substances.
- The blue copper sulfate solution loses its color, indicating a reaction has taken place.
Word Equation for the Chemical Change
- The chemical change can be represented by the following word equation:
- Iron + Copper Sulfate → Iron Sulfate + Copper
Explanation of the Reaction
- In this reaction, iron (Fe) displaces copper (Cu) from copper sulfate (CuSO₄) because iron is more reactive than copper.
- This is an example of a displacement reaction, where a more reactive element replaces a less reactive element in a compound.
- The iron nail reacts with the copper sulfate solution, forming iron sulfate (FeSO₄), which is typically pale green, while copper metal is deposited on the nail, giving it a reddish-brown appearance.
- This reaction showcases the reactivity of metals and how they can participate in chemical transformations.
