Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
GCSE / high school (CBSE class 10): CO₂ from marble chips and dilute HCl in a conical flask, carried by a delivery tube through a one-hole bung into limewater in a test tube.
What the template shows
- Bubble the gas through limewater: it turns milky
- One-hole bung
- Marble chips + dilute HCl
- CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂
- Delivery tube
- Ca(OH)₂(aq), tube end below the surface. Turns milky: Ca(OH)₂ + CO₂ → CaCO₃ + H₂O. A lot more CO₂ makes it clear again (Ca(HCO₃)₂)
- Reaction setup
Drawn with 12 shapes – every one editable in MolDraw.
