Caption:
Zinc reacting with lead (II) nitrate, 2 of 4. Zinc coil was placed in a test tube (Photo 1). 0.5 M solution of lead (II) nitrate solution was then added to the test tube. Since zinc is more reactive than silver, a single-displacement reaction occurred: Zn + Pb(NO3)2 -> Pb + Zn(NO3)2. Photo 2 was taken few seconds after adding lead nitrate, Photo 3 - after about 2 min, Photo 4 - after about 12 min.
