When carbon dioxide is passed through lime water, _______ is formed, w...
Introduction
When carbon dioxide (CO₂) is bubbled through lime water, a chemical reaction occurs, resulting in the formation of calcium carbonate (CaCO₃). This process is a classic experiment used to demonstrate the presence of carbon dioxide.
Reaction Process
- Lime water is a dilute solution of calcium hydroxide (Ca(OH)₂).
- When CO₂ is introduced, it reacts with calcium hydroxide to form calcium carbonate:
Ca(OH)₂ + CO₂ → CaCO₃ + H₂O
Formation of Calcium Carbonate
- Calcium carbonate is only slightly soluble in water, leading to its precipitation.
- The solid calcium carbonate appears as a white precipitate, making the lime water appear milky.
Significance of the Milky Appearance
- The cloudiness or "milky" effect indicates a positive test for carbon dioxide.
- This experiment is commonly used in educational settings to illustrate gas reactions and solubility concepts.
Conclusion
In summary, when carbon dioxide is passed through lime water, calcium carbonate is formed, which makes the lime water milky. This experiment is not only straightforward but also serves as a fundamental demonstration of chemical reactions involving gases and their products.

- When carbon dioxide is passed through lime water, calcium carbonate is formed. This makes the lime water look milky.
- It's like when you mix milk and water together, they create a milky liquid.
- In this case, mixing carbon dioxide with lime water creates a milky substance called calcium carbonate.
