This process supplanted the earlier Hunter process, which instead used molten sodium to extract the target metal. For 10 points each:
[10h] Name this process, which uses molten magnesium to reduce the tetrachloride of a certain medal to its pure form.
ANSWER: Kroll process
[10e] The Kroll process is used to purify this metal, which is often used in airplanes and prosthetic joints due to its strength and lightness. This element’s dioxide is used as a white pigment in sunscreen.
