Displacement reaction. Magnesium coil was added to a test tube containing a 0.2M copper (II) sulfate solution. Since magnesium is more reactive than copper, a single-displacement reaction occurred. Copper metal and magnesium sulfate formed as a result: Mg + CuSO4 -> Cu + MgSO4. In this sequence Photo 1 was taken seconds after the coil was added, Photo 2 was taken after about 1 min, Photo 3 was taken after about 6.5 min, Photo 4 was taken after about 1 hour. Note hydrogen gas bubbles that were produced in a secondary reaction. Photo 4 of 4.
