Verifikasi Deret Aktivitas

Menguji reaktivitas logam dengan reaksi perpindahan

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

Tujuan

Verifikasi deret aktivitas elektrokimia dengan menguji apakah logam dapat memindahkan logam lain dari larutan.

Latar Belakang

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.

Peringatan Keselamatan

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

APD yang Diperlukan

Peralatan

Test tubes and rack Sandpaper Forceps Timer

Prosedur

1

Sand all metal pieces until shiny to remove oxide layers.

3 menit
2

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

3 menit Wear gloves
3

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

5 menit
4

Test iron in CuSO₄ solution. Observe and record.

5 menit
5

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

5 menit
6

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

5 menit
7

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

4 menit

Hasil yang Diharapkan

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.

Pembersihan

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