Which metals will act spontaneously as a reducing agents with silver iodine but not with with silver sulfide
Metals such as zinc, iron, and aluminum will act spontaneously as reducing agents with silver iodine but not with silver sulfide.
Zinc, for example, can react with silver iodine according to the following reaction:
Zn + AgI -> ZnI2 + Ag
However, zinc cannot react with silver sulfide because silver sulfide is more stable and less reactive than silver iodine.
