A chemical change occurred which is evidenced by the change in color of the solution.
Explanation: The addition of iron shavings to the copper (II) sulfate solution resulted in a chemical reaction where the iron displaced the copper in the compound, forming iron sulfate and copper metal. This is supported by the observed change in color of the solution.
The diagram shows a test tube of pure copper (II) sulfate, CuSO4, solution before, during, and after the addition of iron, Fe, shavings.
Which of the following correctly makes and supports a claim about the change that occurred?
Type Answer HERE:
A physical change occurred which is evidenced by the change in color of the solution.
A chemical change occurred which is evidenced by the change in color of the solution.
