Hedef

Bakır elektrotlar kullanarak bakır sülfat çözeltisinin kantitatif elektrolizini gerçekleştirmek ve Faraday'ın birinci elektroliz yasasını doğrulamak.

Arka Plan

When copper sulfate solution is electrolyzed with copper electrodes, copper is deposited at the cathode and dissolved from the anode. By measuring mass changes and current, Faraday's law can be verified: the mass of substance deposited is proportional to the charge passed.

Güvenlik Uyarıları

  • Copper sulfate is toxic if ingested
  • Wear gloves when handling solutions
  • Handle electrical connections with dry hands

7

Calculate the charge passed (Q = I x t). Calculate theoretical mass deposited using Faraday's law: m = (M x Q) / (n x F). Compare with actual mass change.

Beklenen Sonuçlar

The cathode should gain mass and the anode should lose approximately the same mass. At 0.5 A for 20 min: Q = 600 C, theoretical mass = (63.55 x 600) / (2 x 96485) = 0.197 g. Measured value should be within 10%.

Temizlik

Dispose of copper sulfate solution in heavy metal waste. Rinse and store copper strips. Clean the beaker and equipment.
