Between which substances the chemical reaction will take place: a) zinc and ferrum (II) sulfate solution; b) copper and plumbum (II) nitrate solution? Write the reaction equations in molecular and abbreviated ionic forms.
A chemical reaction will occur between zinc and iron (II) sulfate, because zinc is more to the left in the metal stress series than iron. Consequently, its activity is greater. In the case of copper and lead nitrate, the situation is the opposite: copper is located to the right of lead and cannot displace it from its salt. The reaction will not work.
Molecular form of recording the reaction: Zn + FeSO4 = ZnSO4 + Fe.
Abbreviated ionic form of reaction: Zn + Fe / 2 + = Zn2 + / + Fe.
