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. Both the beakers ‘A’ and ‘B’
• B. Beaker ‘A’
• C. Beaker ‘B’
• D. In none of the beakers

Answer 1

The correct option is B 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.
