What is the net ionic equation for the reaction of copper(II) ion with iron?

Answer 1

# 1 Cu^(+2) + 1 SO_4^-2 + 1 Fe^0 -> 1 Fe^(+2) + 1 SO_4^-2 + 1 Cu^0# ionic equation.
# 1 Cu^(+2) + 1 Fe^0 -> 1 Cu^0 + 1 Fe^(+2)# net ionic equation.

The water #H_2O# does not ionize or change, so it is not part of either the ionic equation or the net ionic equation.

The sulfate ion #SO_4^-2# does not change so, while it part of the ionic equation, it is not part of the net ionic equation.

When copper(II) ion reacts with iron, the net ionic equation is as follows: Cu^2+(aq) + Fe(s) -> Cu(s) + Fe^2+(aq)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
