4. Reactions of Metals with Other Metal Ions What, if anything, did you observe in each of the following trials? Write an equation for the reaction if one occurred. Iron with ${\mathrm{CuSO}}_4$ solution: $\mathrm{Fe}+{\mathrm{CuSO}}_4?$ $\times$ Copper with ${\mathrm{FeSO}}_4$ solution: $\mathrm{Cu}+\mathrm{FeSO}?$ Copper with ${\mathrm{AgNO}}_3$ solution: ${\mathrm{Cu}}_{+}{\mathrm{AgNO}}_3$ When a metal atom becomes an ion, or an ion becomes an atom, there is a transfer of electrons. In the preceding reactions, draw circles around the metal atoms which lost electrons and boxes around the metal ions which gained them (reactants). Which is the more active: (a) iron or copper, (b) iron or silver, (c) silver or copper? Arrange the three metals in order of decreasing activity. Arrange all of the metals tested in all parts of this experiment, including hydrogen, in order of decreasing activity.
