Question

which of the following metals do not evolve H2 from dil. acid 1)A(E°A+/A=0.25V)
2)B(E°B/B+=+0.22V)
3)C(E°c+/c=-0.30V)
4) D(E°D/D+=+0.44)..here E°=electrode potential

Answer 1

Answer of this quedtion is 1

Answer 2

Answer:

option 1

Explanation:

Comparing the reduction potential with standard Hydrogen Electrode,

Comparing the reduction potential with standard Hydrogen Electrode,The one having higher reduction potential (SRP)will not allow H+ to be reduced. Thus, there'll be no production of H2.

Comparing the reduction potential with standard Hydrogen Electrode,The one having higher reduction potential (SRP)will not allow H+ to be reduced. Thus, there'll be no production of H2.[The metals which have negative SRPs , can only liberate H2 ]

Comparing the reduction potential with standard Hydrogen Electrode,The one having higher reduction potential (SRP)will not allow H+ to be reduced. Thus, there'll be no production of H2.[The metals which have negative SRPs , can only liberate H2 ]now, considering the options given (Aakash Study package) , the answer will be option 1
