how to make your own nitric acid

[Irons]

Hi Irons,
So then, is there any way the combine Calcium Hydroxide and sodium nitrate and come up with Calcium nitrate?

Neither would precipitate out, so it would be a mess. The whole point of not using Sodium Nitrate is to eliminate any chloride in the resulting Nitric. If you use reagent grade Sodium Nitrate it's not a problem except for the spectator ions present in solution. Using Cacium Nitrate and Sulfuric Acid gives a very clean solution as the resulting Calcium Sulphate fairly insoluble.

Phosphoric Acid is made on an industrial scale in FL using Sulfuric Acid and Rock Phosphate and there are Hills of Gypsum (Calcium Sulphate) as a byproduct.

I think the Sub-zero stuff that Shor sells is still Sodium Nitrate.

The granules are the same appearance. The smell is the same. The density and the powder flow rate seem the same. They act the same way, chemically.

Gldman on e-bay claims they are different. But what other chemical can make Nitric?
