In one of their less evil exploits, Nazi company IG Farben used calcinized dolomite to purify this metal. This element is usually the catalyst of the pinacol coupling. This element is reacted with titanium tetrachloride to give pure titanium in the Kroll process. In ether solvents, this element will interchange between a synthetically useful compound and its dihalide in the (*) Schlenk equilibrium. Along with sodium and calcium, this metal's sulfate acts as a desiccant. Organometallic reagents with this metal are named for Grignard [green-YARR]. This metal's sulfate is often added to foot soaks as epsom salt. This is the second lightest alkaline earth metal after beryllium. For 10 points, name this element with atomic number 12 and symbol Mg.
