The ions Na+ and Ag+ have similar radii. Aqua ion of which of these metals is the stronger acid? Why?
Lewis acids are the electron acceptors.
Na+ has a very stable noble gas electronic configuration and hence it has very less tendency to gain electrons.
While Ag+ also has stable configuration but is can gain the electrons more easily than Na+ and thus Ag+ is stronger lewis acid
