Sodium bifluoride has a number of applications in industry. Solid carbon reacts with oxygen gas to form carbon dioxide gas. Magnesium is a naturally occurring mineral. Both are white solids. Magnesium atoms lose 2 electrons to form a Mg2+ ion, and fluorine atoms gain 1 electron to form a F- ion. If sodium is burnt in air the result is white sodium peroxide, Na 2 O 2, together with some sodium oxide, Na 2 O, which is also white. However, other compounds are present in table salt, depending on its source or additives that may be included before packaging. Magnesium and fluorine will produce magnesium fluoride by ionic bonding. An interval of at least 2 hours is advisable between administration of sodium fluoride and magnesium salts.
