What are s-s bonds?

Presumably you mean a sulfur-sulfur bond?


Peroxide bonds, #O-O#, are known; what is the oxidation state of #O# here?

Polysulfide bonds are much more common. The next time you are in a lab, get some elemental sulfur, i.e. #S_8#, and drop some in water. As you probably know, sulfur is practically insoluble in water. Add a bit of sulfide salt, say #Na_2S#. The sulfur will go up magically. Why?

Elemental sulfur is reduced by sulfide to give a polysulfide salt:

#S_8(s) + S^(2-) rarr ""^(-)S-S-S-S-S-S-S-S-S^-#

The chain length can vary.
