Zn gives 
gas with 
and HCl but not with 
because:
A
Zn act as oxidising agent when react with 
B
is weaker acid than 
and HCl
C
In electrochemical series, Zn is above hydrogen
D
is reduced in preference to hydronium ion
Text Solution
Verified by ExpertsThe correct answer is:
D
In electrochemical series, Zn is present above 
. So; it liberates hydrogen gas from dilute 
but 
is oxidising agent. So, it oxidises 
and 
is itself reduced.
