Question

In which of the following beaker displacement reaction will take place and why ? 1 Beaker A - copper sulphate + zinc granule
2 Beaker B - iron sulphate + copper turning 3 Beaker C - zinc sulphate + copper turning

Answer 1

Answer:

b one

......... .........

Answer 2

Displacement reaction takes place in 1 Beaker A - copper sulphate + zinc granule.

• The complete reaction between copper sulphate and zinc granules is - CuSO4 + Zn --> ZnSO4 + Cu.
• In the reaction, CuSO4 is copper sulphate, Zn represents zinc granules, ZnSO4 stands for zinc sulphate and Cu stands for copper.
• Copper ions are displaced by zinc ions. This reaction is a single displacement reaction.
• The reason for the occurrence of specifically one reaction among given options is the reactivity of metals.
• Zinc is more reactive in comparison to copper and iron.
• Also, copper is the least reactive. Thus, copper is unable to displace iron and zinc.
• Zinc being highly reactive replaced copper from its sulphate solution.
• The double displacement reactions are the ones where both the ions are interchanged with each other.
