1       Iron is more reactive than copper. If a piece of iron is put into copper sulphate solution,
what would you see?

A       Brown copper would appear on the iron.

B       Blue copper would appear on the iron.

C       Nothing would happen.

D       the iron would dissolve completely.

zinc + tin sulphate ®

A       zinc + tin sulphate

B       zinc + zinc sulphate

C       tin + zinc sulphate

D       tin + zinc chloride

 

3       Copper is more reactive than silver. Iron is more reactive than copper. This means that:

B       silver will react with iron nitrate solution.

C       iron will react with silver nitrate solution.

D       silver will react with copper nitrate solution.

 

4       Zinc reacts with copper sulphate solution and silver nitrate solution. This means that zinc:

A       is more reactive than copper and silver.

B       is less reactive than copper and silver.

C       is less reactive than copper but more reactive than silver.

D       is less reactive than silver but more reactive than copper.
