Evidence of Chemical Reaction

Part C

R2 Cu metal is now coated with Ag and the solution is beginning to take on a slightly blue tint

Slide 6

Evidence of Chemical Reaction

Evidence of Chemical Reaction

Part C

R3 HCl solution begins to vigorously bubble when the Mg ribbon is added. Gases are evident as they wisp through the air into the collecting tube; gas is flammable
