CO₂ ve Kireç Suyu Testi

Kalsiyum hidroksit ile karbondioksit tespiti

Gas Laws Beginner (Middle School) 20 dak ~$5,00

Hedef

Karbonat-asit tepkimesinden karbondioksit gazı elde etmek ve kireç suyu testi ile kimliğini doğrulamak.

Arka Plan

When baking soda (sodium bicarbonate) reacts with vinegar (acetic acid), CO₂ gas is produced. Bubbling this gas through limewater (calcium hydroxide solution) produces a characteristic white milky precipitate of calcium carbonate, confirming the presence of CO₂.

Güvenlik Uyarıları

  • Limewater is mildly irritating — avoid eye contact
  • CO₂ is an asphyxiant in large quantities — work in ventilated area

Malzemeler

  • Baking soda (NaHCO₃) (10 g)
  • White vinegar (50 mL)
    5% acetic acid
  • Limewater (Ca(OH)₂ solution) (100 mL)
    Clear, saturated

Ekipman

Erlenmeyer flask (250 mL) Rubber stopper with delivery tube Test tubes Rubber tubing

3

Add 50 mL of vinegar to the flask. Quickly insert the stopper with delivery tube.

2 dak Vigorous effervescence
4

Direct the delivery tube into the limewater. Bubble the CO₂ through for 2-3 minutes.

5

Observe the limewater turning milky white as calcium carbonate precipitate forms.

6

Continue bubbling. If enough CO₂ passes through, the solution may turn clear again as soluble Ca(HCO₃)₂ forms.

Beklenen Sonuçlar

The clear limewater turns milky white due to CaCO₃ precipitation: Ca(OH)₂ + CO₂ → CaCO₃ + H₂O. With excess CO₂, the milkiness clears: CaCO₃ + CO₂ + H₂O → Ca(HCO₃)₂.

Temizlik

Neutralize remaining vinegar solution. Dispose of limewater down the drain. Rinse all equipment.
