Can I save a dying lime tree?
slaked lime = calcium hydroxide = Ca(OH)2 lime = calcium oxide = CaO limestone has calcium carbonate = CaCO3 When you heat limestone (CaCO3), it releases carbon dioxide and leaves behind lime (calcium oxide): CaCO3 --> CaO + CO2 When you slake (mix) lime with water, you get slaked lime: CaO + H2O --> Ca(OH)2
both are Ca(OH)2. Lime water is the diluted version....When you slake a lime an leave it for a few months, there will be a layer of water (providing you used a sufficient amount) ontop of the slaked lime putty. this water is limewater and is clear but contains tiny particles in suspension. The putty is what we refer to as slaked lime.
