Question

Beaker A contains $CuS{O}_4$ solution and zinc pieces. Beaker B contains $ZnS{O}_4$ solution and copper pieces. Chemical reaction will take place in -

• A. Beaker B
• B. None of the beakers
• C. Both the beakers A and B
• D. Beaker A

Answer 1

The correct option is D Beaker A

The element zinc is higher than copper in the reactivity series. zinc is more reactive than copper.

Therefore, zinc displaces the copper ions in $CuS{O}_4$ to form a stable compound $ZnS{O}_4$ and Cu gets deposited at the bottom of the beaker A.

Further, in beaker B there would not be any reaction as copper is lesser reactive than zinc.
