A
more reactive metal will displace a less active metal from a solution.
For example, if you place magnesium in a solution of copper sulfate, the
magnesium will dissolve and the copper will be deposited on the bottom
of the container. This can be represented by a word equation:
magnesium
+ copper sulfate
magnesium sulfate
If
you place calcium in a solution of zinc nitrate, the calcium will dissolve
and zinc will be deposited on the bottom of the container. The word equation
for this reaction is as follows:
calcium
+ zinc nitrate
calcium nitrate + zinc
However
if the metal placed in the solution is less reactive than the metal part
of the solution then a chemical reaction does not occur.
copper
+ aluminium nitrate
no reaction
Complete
the following word equations:
tin
+ copper nitrate
iron
+ tin sulfate
aluminium
+ silver nitrate
