Question

Name a metal which does not displace Hydrogen from dilute acid solutions.

Answer 1

• The metal which is less reactive than Hydrogen does not displace Hydrogen from the dilute acid solution.
• Or, the metals which are placed below hydrogen in the reactivity series cannot displace hydrogen from acids.
• In the activity series, the metal placed below hydrogen is Copper, Mercury, Silver, Gold, and Platinum.

Therefore, Copper metal does not displace hydrogen from dilute acid solutions.
