Verificación de la Serie de Actividad

Prueba de reactividad metálica con reacciones de desplazamiento

Electrochemistry Beginner (Middle School) 30 min ~$12,00

Objetivo

Verificar la serie de actividad electroquímica comprobando si los metales pueden desplazar a otros metales de la solución.

Antecedentes

A more reactive (more easily oxidized) metal will displace a less reactive metal from its salt solution. By testing multiple combinations, students can experimentally construct the activity series: Zn > Fe > Cu > Ag.

Advertencias de seguridad

  • Silver nitrate stains skin permanently
  • Copper sulfate is toxic
  • Wear gloves when handling solutions

EPP requerido

Materiales

  • Zinc strips (3 pieces)
    Small pieces
  • Iron nails (3)
    Clean steel nails
  • Copper strips (3 pieces)
  • Copper(II) sulfate solution (50 mL)
    0.1M
  • Iron(II) sulfate solution (50 mL)
    0.1M
  • Zinc sulfate solution (50 mL)
    0.1M
  • Silver nitrate solution (30 mL)
    0.1M

Equipamiento

Test tubes and rack Sandpaper Forceps Timer

Procedimiento

1

Sand all metal pieces until shiny to remove oxide layers.

3 min
2

Place 10 mL of each metal salt solution into labeled test tubes. You need: CuSO₄, FeSO₄, ZnSO₄, and AgNO₃.

3 min Wear gloves
3

Test zinc in CuSO₄ solution. Observe for 5 minutes and record changes on the metal and in the solution.

5 min
4

Test iron in CuSO₄ solution. Observe and record.

5 min
5

Test copper in ZnSO₄ solution. Observe and record (expect no reaction).

5 min
6

Test copper in AgNO₃ solution. Observe silver crystals forming on the copper.

5 min
7

Compile results into a reactivity table and rank the metals from most to least reactive.

4 min

Resultados esperados

Zinc displaces copper (blue solution fades, copper deposits on zinc). Iron displaces copper (blue fades slower). Copper does not displace zinc. Copper displaces silver (silver crystals grow). Order: Zn > Fe > Cu > Ag.

Limpieza

Collect silver waste separately in heavy metal container. Dispose of copper waste properly. Rinse metal pieces and test tubes.
