Co2+CaCo3+H2o→ Answers this question |
|
Answer» Explanation: Carbon dioxide reacts with limewater to form calcium CARBONATE, which precipitates out of the solution. The carbon dioxide and limewater react to produce calcium carbonate and water. Calcium carbonate is chalk, and when it is produced, it precipitates and solid particles of chalk appear. The appearance of this solid makes the liquid appear ‘MILKY’. The white milky suspension/precipitate is caused by the formation of calcium carbonate. The CHARACTERISTIC test for CO2, is checking that the limewater is milky. This is because chalk is precipitating in the limewater. Bubbling carbon dioxide through the solution for an extended PERIOD of time makes the solution BECOME clear and colourless. This happens as the carbon dioxide forms acidic carbonic acid when it dissolves in the water, the carbonic acid (H2CO3) reacts further with the calcium carbonate: CO2 + H2O ——> H2CO3H2CO3 +CaCO3 ——–> Ca(HCO3)2 Ca(HCO3)2 = calcium hydrogen carbonate which is soluble in water. |
