Name two metals which will displace hydrogen from dilute acids, and two metals which will not.
In displacement reactions,
- Metals which lie above Hydrogen in the reactivity series can displace it from Dilute acids
- Those that lie below hydrogen in the reactivity series cannot .
Let’s look at the reactivity series:
Any of the metals in the series placed above Hydrogen can displace it from its acids.
- Two such metals are - K (Potassium) and Na (Sodium)
Any of the metals in the series placed below Hydrogen will not be able to displace it from its acids.
- Two metals which will not displace hydrogen are - Hg (Mercury) and Ag (Silver)
