What happen when co2 gas is passes through a solution of slaked lime?Explain. |
|
Answer» Slaked lime mean calcium hydroxide [Ca(OH)2] CO2 +Ca(OH)2 ➡️ CaCO3 The CaCO3 (solution) is Milky white in colour. So that when CO2 passes through solution of slaked lime the solution turns Milky When the carbon dioxide is passing through the slaked lime solution, it turns milky when the calcium carbonate and calcium bicarbonate is formed. The chemical reaction can be expressed as: When calcium hydroxide is treated with carbon dioxide, the calcium carbonate and water is formed, then carbon dioxide is released This is one of the chemical tests for\xa0carbon dioxide. That is called as lime water test. When lime (CaO) reacts with water it forms slaked lime\xa0. When the carbon dioxide is passing through the slaked lime solution, it turns milky when the calcium carbonate and calcium bicarbonate is formed.The chemical reaction can be expressed as: When calcium hydroxide is treated with carbon dioxide, the calcium carbonate and water is formed, then carbon dioxide is released. |
