1.	Which one of the following statements is wrong ?A. The electrode potential is called standard electrode potential if the electrode is set up in 1 M solution at 298 KB. The electrode potential of Pt `H_(2 "(1 atm)") \| H^(+) (1M)` is taken as zeroC. Metals which have higher standard electrode potential than N.H.E. react with 1 M `H_(2)SO_(4)` to give `H_(2) ` gasD. Greater the oxidation potential of a metal , more active is the metal .
Answer» Correct Answer - C Metals with higher oxidation potential (lower reduction potentials) react with acids to give `H_(2)` gas .
