The hydratation of concentrated OH- and Na+ ions (by dilution) is exothermic, it gives an energetically prefered state of matter.
(Hydratation is the extra surrounding of the ions by polar water molecules of the solvent).

What is a lime deposit?
A geological area of limestone.
What compossition does limestone have?
lime sediments (calcite)
What is a sentence using endothermic and exothermic?
Plants are endothermic because they use photosynthesis as their means of obtaining energy and endothermic means energy obtaining. A candle flame would be considered exothermic because it releases heat.
Is calcium sulphate and lime the same product?
No. Slaked lime is Ca(OH)2 and quicklime is CaO. Limestone is CaCO3 . CaSO4 when hydrated would be gypsum. It is not lime.
Explain the advantages of using slaked lime instead of powdered limestone for neutralising acidic soil?
Slaked lime is much more alkaline and effective at reducing acidity quickly - it is Ca(OH)2 whereas powdered limestone is CaCO3 and not as alkaline/basic. CO2 is also given off when the limestone reacts with the acid. Water is given of when slaked lime reacts. Mathematically it takes 100 g of limestone to 73g of HCl (as an example) where it would take only 74g of slaked lime per 73g HCl.
What is the limestone cycle?
This is the cycle which tyrns lime stone to - quiclime form this to -Slaked lime from this to - lime water an this turns into limestone and a cycle is created.
Is decomposition of limestone endothermic or exothermic?
endothermic
What is lime obtained from?
limestone
What is the formula of creating quicklime from limestone?
quick lime is CaO and limestone is CaCO3 and the method to prepare limestone out of quick lime is just heat the limestone. CaCO3--------CaO + CO2 HEAT
What gave limestone the name limestone?
Limestone is called limestone because it has lime in it from the sea water it if formed in.
How do you think slaked lime is manufactured from limestone?
Yes, slaked lime is manufactured from limestone: CaO + H2O = Ca(OH)2
What are the types of limestone in the Caribbean?
Jurassic Coralline Limestone and Oolitic Lime Stone
Does limestone help plants grow?
No but lime does
What kind of rock can be formed by lime?
limestone
What is limestone made up of?
lime and stone
What is a lime deposit?
A geological area of limestone.
What compossition does limestone have?
lime sediments (calcite)
