Question

which the following metals do not evolve h2 gas on reaction with dil acid a) 0.25 b)0.22 c)-0.30 d)0.44

Answer 1

Explanation:

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.

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 ]

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

(as option 3, option 4, option 2 have negative SRPs)
