Question

Q-Zinc reacts with dilute hydrochloric acid to librate -
a. hydrogen
b. chlorine gas
c. water gas
d. hydrogen and chlorine gas​
"Answer it correctly"

Answer 1

Answer:

Explanation:

Zinc liberates hydrogen gas when reacted with dilute hydrochloric acid whereas copper does not because it depends on the reactivity of metal to get the hydrogen gas as the product with dilute acid. When zinc react with "dilute hydrochloric acid" it forms zinc chloride with hydrogen gas.      

But same reaction does not occur with copper metal because copper is less reactive than hydrogen. Therefore, copper cannot replace hydrogen from "hydrochloric acid" to form "copper chloride" and hydrogen like zinc.
