Hydrated lime (calcium hydroxide, Ca(OH) 2) and quicklime (calcium oxide, Ca(OH) 2) generally are not recommended for treating surface waters because they are corrosive, difficult to control, and may not be legal to apply.Hydrated lime and quicklime have been used for acid neutralization because less is needed (they have higher neutralizing values than pure limestone), but both are caustic.

Jun 10, 2008· The reactive lime fraction did not influence magnesium concentrations in the media, even as the limestone continued to react. While the residual lime fraction was a source of magnesium under acidic conditions, reducing the acidity of the fertilizer solution negated the residual lime as a magnesium source.

"Limestone is a very common rock type...but geologists didn't really know how it formed until the 1970s. The connection between limestone and life was well established - limestone is often richly fossiliferous - so it seemed likely that somehow sea life produced limestone by chemically removing dissolved lime (CaCO3, calcium carbonate to a chemist; calcite to a geologist) from the water and ...
