What are the properties and uses of periodic acid and mannitol hexanitrate? Periodic acid, also known as periodate or meta-periodic acid, has the chemical formula HlO4·2H2O. It appears as colorless or white crystals with no odor and deliquescent properties. It is primarily u.....
Although its formula (H2O) seems simple, water exhibits very complex chemical and physical properties. For example, itsmelting point, 0 °C (32 °F), andboiling point, 100 °C (212 °F), are much higher than would be expected by comparison withanalogouscompounds, such ashydrogen sulfideand...
Ordinary H2O is not good enough; you need this nostrum which is supposed to have the the chemical formula H30.OH!—which the developer, perhaps having been away from Chemistry for a while, writes as H30.OH. Anyone who has completed a high school Chemistry course will recognize this as a...
However, both water sources have issues with Fe and Mn ions contamination. Fe and Mn ions can be removed by chemical or biological treatments. However, the results may be different due to many factors that affect the treatment itself. Show moreView article...
