Question
Fe is reacted with 1.0 M HCl. Eo for Fe / Fe2+ = + 0.34 V. The correct observation(s) regarding this reaction is/are :
Options
A.Fe will be oxidised to Fe2+
B.Fe2+ will be reduced to Fe
C.since e.m.f. > 0, the reaction shall occur
D.since e.m.f. > 0, the reaction shall not occur.
Solution
EoFe2+/Fe > EoH+/H2 ; So, Fe oxidised into Fe2+
Fe + 2H+ → Fe2+ + H2 ECell = +ve.
Fe + 2H+ → Fe2+ + H2 ECell = +ve.
