In the experiment lead became reddish brown, some of it fell and sank to the bottom. And the copper sulfate became light green instead of dark green, this is confusing me, because it seems as if they both reacted, but lead is more reactive than copper, and as I know , a more reactive metal will displace a less reactive metal from its compounds, can you please explain what happened here? and if possible right the equation.

The reddish brown deposition upon lead is Cu.
However, the green colouration is probably due to impurities present in the lead (Fe or Ni) whose sulphates are green.
PbSO4 is white and is insoluble in water.

what about the temp.of the mixture the melting temp. of lead is 327 C while the melting temp.of copper is1083 C..you should get the melting point of copper sulphate and if it is more than 327 C,that means the lead will dissolve in copper sulphate..as I know ..the lead is a heavy metal and is hard to react with nonmetals and salts but it is easily combine with other metals with high temp.to form alloys
