Which one of the following statements is wrong ?

Answer»

The electrode potential is called standard electrode potential if the electrode is set up in 1 M solution at 298 K
The electrode potential of
Pt `H_(2 "(1 atm)") | H^(+) (1M)` is TAKEN as zero
Metals which have higher standard electrode potential than N.H.E. REACT with 1 M `H_(2)SO_(4)` to give `H_(2) ` gas
Greater the oxidation potential of a METAL , more ACTIVE is the metal .

Solution :Metals with higher oxidation potential (lower reduction potentials) react with acids to give `H_(2)` gas .
