Question

A compound containing this element is electrolyzed in a solution of molten calcium chloride for purification in the Fray-Farthing-Chen Cambridge process. In 1972, Kenichi Honda and Akira Fujishima discovered that an oxide of this element can catalyze the decomposition of water. The thio sol-gel process produces thin films of this element’s sulfide, which can used to form the cathode in solid-state lithium batteries. The (*) Petasis reagent (-5[1])is prepared by reacting alkyllithium with the dichloride of a metallocene containing this metal. This metal is extracted from rutile in the Kroll (10[1])process. Both zinc and this metal’s dioxide are white pigments commonly added to mineral sunscreen products. For 10 points, name this corrosion-resistant metal with the chemical symbol Ti ■END■ (10[1])

ANSWER: titanium [or Ti until “Ti” is read; accept titanium dioxide or titanium(IV) oxide or titania; accept titanocene]
