Question
Assertion: Different metals have different reactivities with water and dilute acids.
Reason: The reactivity of a metal depends on the reactivity 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.
Hint:
Both A and R are true, and R is the correct explanation of A
The correct answer is: Both A and R are true, and R is the correct explanation of A.
Different metals have different reactivity with various mineral acids as the metal on top of the series react easily with acids while metals present at the bottom are unreactive to acids or water.
Some metals give up their electrons more readily than others and are, therefore, more reactive. Metals can be ranked according to their level of reactivity to form the metal reactivity series.
