Question

state whether a displacement reaction will occur if the following are mixed. give reasons. give the reaction.a.copper sulphate and zincb.copper sulphate and ironc.zinc sulphate and copperd.zinc sulphate and irone.iron sulphate and zincf.iron sulphate and copper

Answer 1

Heya......

Here is your answer

In a displacement reaction, more reactive elements displace less reactive elements from their salt solutions.

A. Yes, in this case displacement reaction will occur as zinc is more reactive than copper and so, it will displace ( substitute) the copper from its aqueous solution.

B. Yes, in this case too displacement will happen as iron element is more reactive than copper and hence it will displace copper from its aqueous solution.

C. No, displacement reaction will not occur here as copper is less reactive than zinc.so, it cannot displace zinc.

D. No, displacement reaction will not occur here as iron is less reactive than zinc so it cannot displace zinc from its salt solution.

Both copper and iron are less reactive

elements than Zinc.

E. yes, displacement reaction will occur and zinc will displace iron from its aqueous solution.

F. No, Copper is less reactive, so it cannot displace iron from its salt solution. hence no displacement reaction will occur.

DISPLACEMENT REACTION OCCUR.

C)

ZNSO4+CU--- NO REACTION

NO DISPLACEMENT REACTION OCCUR.

D)

ZNSO4 +FE-----NO REACTION

NO DISPLACEMENT REACTION OCCUR.

E)

FESO4+ZN----------ZNSO4+FE

DISPLACEMENT REACTION OCCUR.

F)

FESO4 +CU--------NO REACTION

NO DISPLACEMENT REACTION OCCUR.
