Sodium nitrate is the chemical compound with the formula Na N O 3.This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate.
Sodium nitrite works by creating methemoglobin, where the iron atom at the center of the heme group is in the oxidized ferric (Fe 3+) state, which binds with cyanide with greater affinity than its binding to the cytochrome C oxidase, and thus removes it from blocking the metabolic function of mitochondria. [31] Sodium nitrite came into medical ...
The combination of table salt with nitrates or nitrites, called curing salt, is often dyed pink to distinguish it from table salt. [6] Neither table salt nor any of the nitrites or nitrates commonly used in curing (e.g., sodium nitrate [NaNO 3], [7] sodium nitrite, [7] and potassium nitrate [8]) is naturally pink.

A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Also called Pink curing salt #2. It contains 6.25% sodium nitrite, 4% sodium nitrate, and 89.75% table salt. [4] The sodium nitrate found in Prague powder #2 gradually breaks down over time into sodium nitrite, and by the time a dry cured sausage is ready to be eaten, no sodium nitrate should be left. [3]
An example of a topological food web (image courtesy of USDA) [1] The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals. Food webs describe the transfer of energy between species in an ecosystem.
Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. [1] The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature. The name nitrite also refers to organic compounds having the –ONO group, which are esters of nitrous acid .
