Single Replacement Reactions: Activity Series
Li > K > Ba > Sr > Ca > Na > Mg > Al > Mn > Zn > Fe > Cd > Co > Ni > Sn > Pb
The above elements all replace hydrogen from acids.
The most active can replace H from water (Li – Na) . Mg can slowly react with
hot water.
Al – Pb react with acids but not with water.
H > Cu > Ag > Hg > Au
(Cu, Hg, Ag, do not replace H from acids)
Predict whether the following will react, and what the products will be if they do. If no
reaction is predicted, write NR. Balance the equations
