The Activity SeriesAny metal on the list can be oxidized by the ions of elements below it.Cu ( s)+ 2Ag + ( aq) → Cu 2+ ( aq) + 2Ag ( s)Cu is higher on activity series.Zn 2+ ( aq) + Cu( s) → No Reaction Zn is higher on activity series.Notice: The element that ends up as the cation is higher on the activity series.2 Na(s) + Sn2+(aq) → 2 Na+(aq) + Sn(s)A2+(aq) + B(s) → A(s) + B2+(aq)Ch 4 Reactions in Aqueous Solution - 12 -
