What will happen when a block of copper metal is dropped into a beaker containing a solution of 1   M Z n S O 4 ?

Options

  1. AThe copper metal will dissolve with evolution of oxygen gas.
  2. BThe copper metal will dissolve with evolution of hydrogen gas.
  3. CNo reaction will occur.
  4. DThe copper metal will dissolve and zinc metal will be deposited.

Correct answer

C. No reaction will occur.

Step-by-step solution

Zn is above Cu in electrochemical series. So, Zn will reduce Cu 2+ to Cu. Cu + Zn 2+ → No reaction Displacement reaction is feasible in opposite direction only. Cu 2+ + Zn → Zn 2+ + Cu ↓
