Zinc liberates hydrogen gas when reacted with dilute hydrochloric acid, whereas copper does not. Explain why?


#1

Zinc liberates hydrogen gas when reacted with dilute hydrochloric acid, whereas copper does not. Explain why?
Answer:
Zinc is above hydrogen whereas copper is below hydrogen in the activity series of metals. That is why zinc displaces hydrogen from dilute hydrochloric acid, while copper does not.

#2

Zinc is able to displace Hydrogen from hydrochloric acid as it is more reactive than hydrogen while copper is less reactive than hydrogen hence, no reaction takes place.


#3

zinc is more reactive than copper and hydrogen whereas copper is less reactive than hydrogen and zinc
