TaigaWhen carbon dioxide is bubbled through lime water (a solution of calcium hydroxide), it forms a white precipitate of calcium carbonate. This reaction is commonly used as a test for the presence of carbon dioxide. The equation for the reaction is: CO2 + Ca(OH)2 -> CaCO3 + H2O.

What does CO2 and lime water make?
When carbon dioxide reacts with lime water (calcium hydroxide solution), it forms a white precipitate of calcium carbonate. This reaction is commonly used as a test for the presence of carbon dioxide gas.
Which colour does the lime water change to when put in oxygen?
Lime water turns milky or cloudy when exposed to oxygen. This is due to the formation of calcium carbonate as the lime water reacts with carbon dioxide in the air.
What is limewater element or compound?
Limewater is a saturated solution of calcium hydroxide (Ca(OH)2) in water. It is a compound made up of calcium, oxygen, and hydrogen atoms. Lime water turns milky when carbon dioxide is passed through it, due to the formation of calcium carbonate.
What are the word equations for processes that release or store carbon doixide?
The word equation for the process that releases carbon dioxide through respiration is glucose + oxygen -> carbon dioxide + water + energy. The word equation for the process that stores carbon dioxide through photosynthesis is carbon dioxide + water + sunlight -> glucose + oxygen.
When you make lime water why do you filter the calcium hydroxide?
Filtering the calcium hydroxide in lime water removes any undissolved particles or impurities present in the solution. This helps ensure that the lime water is clear and free of solid debris, which could affect the accuracy of experiments or desired applications where a clear solution is needed.
