I came across this value of reduction potential of water while solving a question. Also, I noticed that, for example $$\ce{Ag+ → Ag}$$ has a fixed standard potential, and the same is used when we do it for a reaction like $$\ce{AgCl → Ag + Cl-}$$ Then why here in the reduction of water the value differs from the $\ce{H+ → 1/2 H2}$ reaction?

Standard reduction potential (also known as redox potential, oxidation / reduction potential or ORP) is the tendency of a chemical species to acquire electrons and thereby be reduced. Each species has its own intrinsic reduction potential; the more positive the potential, the greater the species' affinity for electrons and tendency to be reduced.
