Hedef

Yavaş buharlaşma yöntemini kullanarak büyük ve iyi oluşmuş bakır sülfat pentahidrat kristalleri büyütmek; aşırı doygunluk ve kristal kafes oluşumunu göstermek.

Arka Plan

Copper sulfate pentahydrate (CuSO₄·5H₂O) forms beautiful blue triclinic crystals. By preparing a saturated solution and allowing it to evaporate slowly over several days, large single crystals can be grown. The process demonstrates concepts of solubility, supersaturation, and crystal nucleation.

Güvenlik Uyarıları

  • Copper sulfate is toxic if ingested
  • Wear gloves when handling the solution
  • Wash hands thoroughly after the experiment
  • Do not dispose of copper sulfate down the drain

Malzemeler

  • Copper(II) sulfate pentahydrate (50 g)
    Blue crystals
  • Distilled water (200 mL)
    Hot
  • Thread or fishing line (30 cm)
    For seed crystal
  • Pencil or stick (1)
    To suspend seed crystal

Ekipman

400 mL beaker Hot plate Stirring rod Filter paper Funnel

Prosedür

1

Heat 200 mL of distilled water to 60-70°C. Add copper sulfate gradually while stirring until no more dissolves (saturated solution).

2

Filter the hot saturated solution through filter paper to remove any undissolved particles.

3

Pour a small amount into a petri dish and allow it to cool. Select the best small crystal as a seed crystal after 24 hours.

4

Tie the seed crystal to a thread and suspend it from a pencil placed across the top of the beaker of saturated solution.

5

Cover the beaker loosely with filter paper to allow slow evaporation. Place in a vibration-free location.

6

Check daily for crystal growth. Remove any small crystals that form on the thread or beaker walls.

Beklenen Sonuçlar

After 1-2 weeks, the seed crystal should grow into a large blue crystal (1-3 cm) with well-defined facets. The crystal has a triclinic shape with distinct flat faces. Faster evaporation produces many small crystals; slower produces fewer, larger ones.

Temizlik

Collect excess copper sulfate solution and solid for reuse or proper disposal in heavy metal waste. Do not pour down the drain.
