limestone reactivity test

The chemistry of limestone
The lime is white and will have a more crumbly texture than the original limestone. Calcium carbonate does not react with water. Adding water to the lime produces slaked lime (calcium hydroxide) in an exothermic reaction. CaO(s) + H 2 O(l) → Ca(OH) 2 (s)

Feb 01, 2002 · When lime is worked into the soil, a larger portion of its surface area is exposed to the soil allowing for faster reactivity. Lime applied on the soil surface does not react as fast as lime incorporated by tillage, but what other option is there in perennial pasture systems? Surfaceapplied lime moves into the soil at a slow rate.

What happens when acid reacts with limestone? Questions
Jun 15, 2008 · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don''t dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3 ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
