Dissolving titanium dioxide (TiO2) requires strong acids or bases, due to its chemical inertness and high stability. Using hydrofluoric acid (HF) is one common method, as HF reacts with TiO2 to form soluble hexafluorotitanate complexes. However, this method is highly dangerous due to the corrosive and toxic nature of HF. An alternative, safer method involves using concentrated sulfuric acid (H2SO4), which can dissolve TiO2 by converting it into water-soluble titanium sulfate under controlled conditions and elevated temperatures. Nonetheless, these approaches should be undertaken with extreme caution, in a lab setting, with proper safety equipment and procedures in place due to the hazardous nature of the chemicals involved and the risk of generating toxic fumes. It's crucial to consult detailed protocols and safety data sheets before proceeding.

A majority of Infiniti vehicles are produced at Nissan's manufacturing plants in Higashiki Prefecture and Fukuoka. Japan. Some models are also produced at Nissan's Smyrna. Tennessee. and Sunderland. England. plants. Nissan's Aguascalientes plant in Mexico also produces the Infiniti QX50.
