Chemical compound

Magnesium perchlorate is a powerful oxidizing agent, with the formula Mg(ClO₄)_ii. The table salt is also a superior drying agent for gas assay.

Magnesium perchlorate decomposes at 250 °C.^[two] The heat of formation is -568.90 kJ mol⁻ⁱ.^[3]

The enthalpy of solution is quite high, and then reactions are done in big amounts of h2o to dilute it.

It is sold under the trade name anhydrone. Manufacture of this product on a semi-industrial scale was first performed by G. Frederick Smith in his garage in Urbana Illinois, but later at a permanent facility in Columbus, OH called Thousand. Frederick Smith Chemical Co. He sold the magnesium perchlorate to A. H. Thomas Co., now Thomas Scientific, under the trade name Dehydrite.

Uses [edit]

It is used as desiccant to dry out gas or air samples,^[4] ^[5] but is no longer advised, for use as a full general desiccant, due to hazards inherent in perchlorates.^{[half dozen]} It is stale past heating at 220 °C under vacuum.

Magnesium perchlorate and other perchlorates have been constitute on Mars.^[vii] Existence a drying amanuensis, magnesium perchlorate retains water from the atmosphere and may release it when weather are favorable and temperature is to a higher place 273 K. Briny solutions that contain salts such as magnesium perchlorate have a lower melting indicate than that of pure water. Therefore the abundance of magnesium and other perchlorate salts on Mars could support the theory that liquid aqueous solutions might exist on or beneath the surface, where temperature and pressure weather condition would ordinarily cause the water to freeze.

Product [edit]

Magnesium perchlorate is produced by the reaction of magnesium hydroxide and perchloric acid.
