A) \[L{{i}^{+}}\]
B) \[B{{a}^{2+}}\]
C) \[C{{u}^{2+}}\]
D) \[B{{e}^{2+}}\]
Correct Answer: C
Solution :
Key Idea: The ions which lies below\[{{H}^{+}}\]in electrochemical series, displace B^ from solution. \[\because \]\[C{{u}^{2+}}\]lies below\[{{H}^{+}}\]in electrochemical series \[\therefore \]\[C{{u}^{2+}}\]ions displace\[{{H}^{+}}\]when\[{{H}_{2}}\]gas is bubbled in solution containing these ions.You need to login to perform this action.
