Magnesium is an alkaline earth metal of atomic number 12 và it is represented by the symbol Mg. The name Magnesium comes from the Greek word Magnesia. It was first discovered by Joseph đen in the year 1755. It makes up to 13 percent of the planet’s mass & the largest part of the planet’s mantle. Naturally, it occurs in combination with other elements and mostly has the oxidation state of +2. Không tính phí metal can now be produced artificially due to lớn the advancement in science but it is highly reactive. The không lấy phí metal burns with a characteristic brilliant white light. It is the most abundant element by mass in the human body.

Magnesium Hydroxide Formula

Magnesium hydroxide is an organic compound with chemical formula of Mg(OH)2 and occurs naturally as mineral brucite. Brucite is a common alternative sản phẩm of periclase in marble và was first discovered in 1824 by Francois Sulpice Beudant. A fibrous type of Brucite is called nemalite and occurs in fibres but usually elongates but sometimes even takes a crystalline form. Magnesium Hydroxide is located in wood’s Chroma Mines, Pennsylvania. Yellow, blue and white Brucite is found in the Saifullah District of Pakistan. It also occurs in South Africa, Italy, Russia and many more locations. It is prepared by treating the solution of different soluble salts with alkaline water by which a precipitate of magnesium hydroxide is formed .


Structure of Magnesium Hydroxide

The molecular formula of Magnesium Hydroxide is Mg(OH)2 & is formed by the bond formation between Mg+2 ion & two ions of (OH)-1 ion. The IUPAC name of it is Magnesium di hydroxide .

Preparation of Magnesium hydroxide

When a solution of magnesium salts is combined with alkaline water it instigates precipitation of solid magnesium hydroxide. The reaction is as follows:

Mg2+ + 2 OH− → Mg(OH)2

Commercially it is produced by treating lime và seawater. Approximately one ton of magnesium hydroxide is obtained from 600 m3 of seawater. Calcium hydroxide is more soluble in magnesium hydroxide therefore Mg(OH)2 precipitates as a solid. The reaction is as follows:

Mg
O + H2O → Mg(OH)2

Effects on Health

Flushing or drowsiness are side effects of magnesium hydroxide. Consuming this compound on a daily basis can result in electrolyte disturbances. Excessive use can result in nausea, diarrhoea, & abdominal cramping. Symptoms include watery diarrhoea or gastrointestinal irritation may occur. Poisoning causes hypomagnesemia which includes symptoms such as: vomiting, hypotension, confusion, muscle weakness, cardiac arrhythmias, Cardiac arrest, nausea, flushing, thirst, drowsiness, loss of tendon reflexes, respiratory depression, & coma.
