Question

Why is  Iron (lll) and copper (ll) sulfate a single double replacement when they react with one another?

Answer 1

Hello Athena

 

The reaction between iron (III) and "aqueous" copper (II) sulfate is:

 

2Fe (s) + 3CuSO₄ (aq) → Fe₂(SO₄)₃ (aq) + 3Cu (s)

 

In the above reaction, a single element, Fe, is replacing another single element, Cu, in CuSO₄ to form Fe₂(SO₄)₃.  As a result, this is a single replacement reaction.
