Explanation:
Detailed explanation-1: -The nitrates are similar to the carbonates in structure; they are anisodesmic with (NO3)− radicals, and isostructural with calcite . Nitrates can be grouped as minerals of the A(XO3) type, e.g., nitratine: Na(NO3)
Detailed explanation-2: -The most important nitrates are soda nitre, nitre (saltpetre), darapskite, and humberstonite. Among the iodates are lautarite and dietzeite.
Detailed explanation-3: -Some examples of nitrite salts are ammonium nitrite, calcium nitrite, sodium nitrite, and potassium nitrate. Nitrites mainly decompose to N2 and NO. Nitrites may be further reduced to nitrogen by bacteria under some conditions.
