When one element replaces another element in a compound, a single replacement (also known as displacement) reaction has taken place.

The general formula for this reaction is A + BX --> AX + B.

Cu(s) + 2AgNO3(Aq) --> Cu(NO3)2(Aq) + 2Ag(s)

A single replacement reaction will only take place if a more reactive element is replacing a less reactive one

That chart says lower activity...

Replacement Displacement Silver with Inorganic Pigments

Is it possible to color bw film or paper trichrome images one by one with different inorganic pigment chemistry ?
