Didn't get why liberation of H2 affects this
H2 acts as a reducing agent here. Fe3+ formed gets reduced to Fe2+
@Kunwar_Singh bro will not the reason would be HCl is not a very strong oxidising agent ?? So it cannot oxidise +2 to +3 state ??
Your reason is correct , but this is also right isn't ?? @Kunwar_Singh bro
Well, don't you think that both are the same thing? According to me they are the same thing. You are just looking from the other side of equillibrim.
