Finely divided platinum and some other metals will cause a mixture of hydrogen and oxygen to explode at ordinary temperatures. If a jet of hydrogen in air impinges on platinum black the metal surface gets hot enough to ignite the gases, [Mellor 1:325(1946-1947)].
magnesium chloride. Uses. This medication is a mineral supplement used to prevent and treat low amounts of magnesium in the blood. Magnesium is very important for the normal functioning of cells, nerves, muscles, bones, and the heart. Usually, a well-balanced diet provides normal blood levels of magnesium.
This reaction causes the content of magnesium oxide in the resultant anhydrous magnesium chloride to be increased. When the concentration of the magnesium chloride hexahydrate is larger than 70% by weight, a portion of the magnesium chloride hexahydrate may become difficult to dissolve in the reaction mixture.owever, after the recovery of the precipitated magnesium chloride hexammoniate, the remaining aqueous solution containing unreacted magnesium chloride, ammonium salt and ammonia, and having a low temperature, is discharged from the reaction system without recovering it.
