Nitrates are salts or esters of nitric acid, HNO 3, formed by replacing the hydrogen with a metal (e.g., sodium or potassium) or a radical (e.g., ammonium or ethyl).
Calcium nitrate is used in fertilizers; barium and strontium nitrates are used to color fireworks and signal flares; bismuth nitrate is used in making pharmaceuticals.
The presence of nitrates in the soil is of great importance, since it is from these compounds that plants obtain the nitrogen necessary for their growth.

At first sight this looks quite simple and self-evident,--that neutral salts should form neutral ones again and not acid or basic ones,but if this fact is once stated very serious quantitative inferences may be drawn from it, as Richter showed.
For if the symbols A, A, B, B denote at the same time such quantities of the acids and bases as form neutral salts, then if three of these quantities are determined, the fourth may be calculated from the others.
In most of these experiments a slight diminution of weight was observed which exceeded the limit of error distinctly in two cases, viz, silver nitrate with ferrous sulphate and iodic acid.
