Which of the following solutions can be safely stored in a copper vess

1.	Which of the following solutions can be safely stored in a copper vessel ?A. `ZnSO_(4)`B. `AgNO_(3)`C. `AuCl_(3)`D. All of them.
Answer» Correct Answer - A `Cu` cannot reduced `Zn^(2+)` but it reduces `Ag^(+)` as well as `Au^(+3)` ions.
