Magnesium can also be toxic to plants, although this is typically seen only in drought conditions. [47] [48] Space-filling model of the chlorophyll a molecule, with the magnesium ion (bright-green) visible at the center of the chlorin group. In animals, magnesium deficiency (hypomagnesemia) is seen when the environmental availability of ...
Magnesium nitrate reacts with alkali metal hydroxide to form the corresponding nitrate: Mg(NO 3) 2 + 2 NaOH → Mg(OH) 2 + 2 NaNO 3.. Since magnesium nitrate has a high affinity for water, heating the hexahydrate does not result in the dehydration of the salt, but rather its decomposition into magnesium oxide, oxygen, and nitrogen oxides:
Chlorophyll a contains a magnesium ion encased in a large ring structure known as a chlorin. The chlorin ring is a heterocyclic compound derived from pyrrole. Four nitrogen atoms from the chlorin surround and bind the magnesium atom. The magnesium center uniquely defines the structure as a chlorophyll molecule. [8]
The presence of magnesium in chlorophyll was discovered in 1906, [8] and was the first detection of that element in living tissue. [ 9 ] After initial work done by German chemist Richard Willstätter spanning from 1905 to 1915, the general structure of chlorophyll a was elucidated by Hans Fischer in 1940.
Magnesium reacts with haloalkanes to give Grignard reagents, which are used for a wide variety of organic reactions forming carbon–carbon bonds. [99] Magnesium salts are included in various foods, [100] fertilizers [101] (magnesium is a component of chlorophyll [102]), and microbe culture media. [103]
Nitrate is a polyatomic ion with the chemical formula NO − 3. Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. [1] Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate.
Magnesium nitrate – Mg(NO 3) 2; Magnesium oxalate – MgC 2 O 4; Magnesium peroxide – MgO 2; Magnesium phosphate – Mg 3 (PO 4) 2; Magnesium silicate – MgSiO 3; Magnesium sulfate – MgSO 4; Magnesium sulfide – MgS; Magnesium titanate – MgTiO 3; Magnesium tungstate – MgWO 4; Magnesium zirconate – MgZrO 3
Magnesium reacted with an alkyl halide gives a Grignard reagent, which is a very useful tool for preparing alcohols. Magnesium salts are included in various foods, fertilizers (magnesium is a component of chlorophyll), and microbe culture media. Magnesium sulfite is used in the manufacture of paper (sulfite process).
