Chemistry
Assertion (A): Silver is displaced by copper from the aqueous solution of silver nitrate.
Reason (R): Copper is placed below silver in the activity series.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
A is true but R is false.
Explanation — Silver is displaced by copper from the aqueous solution of silver nitrate because copper is more reactive than silver. Hence the assertion is true.
Copper is placed above silver in the activity series. So copper is more reactive and can displace silver. Hence the reason (R) is false.
