Copper reacting with silver nitrate, image 1 of 5. Copper metal wire was immersed into a test tube containing a 0.25M silver nitrate solution. Since copper is more reactive than silver, a single-displacement reaction occurred: Cu + AgNO3 -> Ag + Cu(NO3)2. In this sequence Photo 1 was taken 10 sec after the wire was put into the test tube, Photo 2 was taken after 2.5 min, Photo 3 was taken after 5 min, Photo 4 was taken after 7.5 min, Photo 5 was taken after 20 min.
