make ammonium nitrate

Hi all,

That is the <"same in a lot of countries">, all nitrate compounds are potential explosives, but some give you a bigger bang.

urea (CO(NH2)2)">? Personally I would be much happier <"using urea as a TAN source">, purely in fish welfare terms.

You need the RMM of NH4NO3 = (14 + 4) + (14 + 48) = 80. The NH4 is 18 / 80 = 22.5% and NO3 bit is 62 / 80 = 77.5%. The nitrogen content is 28 / 80 = 35%.

exactly the same way">.

I will make 500ml stock solution for my 75 liter tank, my calculations are that 1ml in the water direction is 0.98ppm. If I use 70 grams of calcium nitrate, I get 0.98ppm. Since this salt is calcium ammonium nitrate, if I use 77 grams, I will get 0.98ppm. Is this true, Darrel?

That is right.

Should be near enough.

Having said that the result from "calcium nitrate tetrahydrate" Ca(NO3)2.4H2O will be pretty close.
RAM
Ca = 40.1, N = 14, O = 16, H = 1
RMM
40.1 + (14*2) 28 + (16 * 6) 96 + (8) + (4 * 16)64 = 236.1 and 40.1 / 236.1 = 17% N and 17 / 15.5 = ~ 1.1 so 10g of Ca(NO3)2.4H2O has the same amount of nitrogen as ~ 11g "NitroChalk".
