A) The copper metal will dissolve and zinc metal will be deposited.
B) The copper metal will dissolve with evolution of oxygen gas.
C) The copper metal will dissolve with evolution of hydrogen gas.
D) No reaction will occur.
Correct Answer: B
Solution :
If a block of copper metal is dropped into a beaker containing solution of \[1MZnS{{O}_{4}},\]no reaction will occur because \[E_{Z{{n}^{2+}}/Zn}^{0}=-0.76V\] \[E_{Z{{n}^{2+}}/Cu}^{0}=+0.34V\] Hence Cu can't displace Zn from \[ZnS{{O}_{4}}\] solution.You need to login to perform this action.
