Thermal decomposition of a carbonate template
Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
GCSE / high school (CBSE class 10): copper(II) carbonate heated in a clamped boiling tube; a delivery tube through a bung carries the CO₂ into limewater in a test tube.
What the template shows
- Heat a metal carbonate and show that carbon dioxide is given off
- Clamp near the mouth
- Not too tight: hot glass expands
- Copper(II) carbonate
- CuCO₃ → CuO + CO₂: green powder turns black. Other carbonates, e.g. ZnCO₃, work the same way
- Bunsen burner
- Heat strongly
- Delivery tube
- Turns milky. Lift the delivery tube out before you stop heating, or limewater sucks back into the hot tube
- Reaction setup
Drawn with 16 shapes – every one editable in MolDraw.
