Chemistry - 14 - The Limewater Limerick-ish
Limewater, a solution clear Of calcium hydroxide That's quickly turned cloudy By carbon dioxide It therefore is a test Of CO₂ as guest And if you are wise You'll know this alkali By CO₂ is neutralised Which makes insoluble white Calcium carbonate And that is the source Of those clouds, of course Ca(OH)₂ plus CO₂ will go To CaCO₃ and also H₂O Calcium hydroxide Plus carbon dioxide To calcium carbonate And some water weight Limewater, it can come From thermal decomposition Of calcium carbonate Calcium oxide made Then just add H₂O To calcium hydroxide go CaCO₃ to CaO plus CO₂ Throw away the CO₂ CaO with water brew Then Ca(OH)₂ we get Limewater solution (That means it's wet) CaCO₃ to CaO plus CO₂ Throw away the CO₂ CaO with water brew Then Ca(OH)₂ we get Limewater solution (That means it's wet)
