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!
 
ya 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.

Check out the hydrobuddy thread if you're looking to make DIY nutes with salts. Hydrobuddy has a bunch of built in formulas you could use, and the recipe listed on the hydrobuddy thread is also pretty good.

To make things easier, you can also make a+b stock solutions (hydrobuddy helps with this) and then add equal parts of the stock solution to the reservoir.
