What will happen when a block of copper metal is dropped into a beaker containing a solution of ?
Choose an option
Show full solutionCorrect option: C
Correct answer
CNo reaction will occur.
Step-by-step explanation
Zn is above Cu in electrochemical series. So, Zn will reduce Cu2+ to Cu.
Cu + Zn2+ → No reaction
Displacement reaction is feasible in opposite direction only.
Cu2+ + Zn → Zn2+ + Cu
Cu + Zn2+ → No reaction
Displacement reaction is feasible in opposite direction only.
Cu2+ + Zn → Zn2+ + Cu
