I am just wondering.. I have chemicals like calcium nitrate, magnesium sulfate. and would like to the percentage of Calcium or Nitrate in calcium Nitrate. Is there any way of knowing the Content of such elements? Thnks!
Good day m8! this means any calcium nitrate i buy will doesnt differ that much in content? just wondering m8 coz i found more cheaper calnitya mean Epsom salt?
Norgessalpeter was the first synthetic nitrogen fertilizer compound to be manufactured. Production began at Notodden, Norway in 1905 by the Birkeland–Eyde process. Most of the world's calcium nitrate is now made in Porsgrunn.
It is produced by treating limestone with nitric acid, followed by neutralization with ammonia:
CaCO3 + 2 HNO3 → Ca(NO3)2 + CO2 + H2O
It is also an intermediate product of the Odda Process:
Ca3(PO4)2 + 6 HNO3 + 12 H2O → 2 H3PO4 + 3 Ca(NO3)2 + 12 H2O
It can also be prepared from an aqueous solution of ammonium nitrate, and calcium hydroxide:
2 NH4NO3 + Ca(OH)2 → Ca(NO3)2 + 2 NH4OH
Like related alkaline earth metal nitrates, calcium nitrate decomposes upon heating (starting at 500 °C) to release nitrogen dioxide:[2]
2 Ca(NO3)2 → 2 CaO + 4 NO2 + O2 ΔH = 369 kJ/mol
I think most of us use Yara calcium nitrate, which is a double salt with 5 calcium nitrate to every 1 ammonium nitrate.Good day m8! this means any calcium nitrate i buy will doesnt differ that much in content? just wondering m8 coz i found more cheaper calnit
