Reacted with a calcium source such as quick lime or limestone to produce dicalcium phosphate. dcp is made by reacting superphosphate with an alkaline agent. the liming agent is mixed with superphosphate and a chemical reaction occurs to have dcp.
It is composed of calcite caco3. the organic matter upon which it settles in lades or seats, are preserved as fossils. over thousands and millions of years, layer after layer is built up adding weight. the heat and pressure causes chemical reaction at the bottom and the sediments turn into solid stone, the limestone.
Quicklime is known by a wide range of names, like unslaked lime, burnt lime, chemical lime, fat lime, or sometimes just lime. quicklime is obtained by burning or heating calcium carbonate, which occurs in natural limestone deposits. this process is one of the oldest chemical operations discovered by man, being used all over the world.
May 02, 2013nbsp018332the chemical reactivity is known to vary between limestone sources, not only because of the differences in crystalline structure but also depending on the nature of the impurities. calcination of caco3 is a highly endothermic reaction, requiring around 755 mcal of
