This metal's hydroxide is used as a binder for phosphate in hemodialysis, and absorption of this element's cation under acidic conditions causes ?
Silicates of this element are found in rocks such as kaolinite and andalusite, and along with manganese, its silicate is found in spessartine. Studies on freshwater snails show that orthosilicic acid aids in the removal of this element in vivo, while several plants resistant to it release organic acids to prevent its uptake. This metal's hydroxide is used as a binder for phosphate in hemodialysis, and absorption of this element's cation under acidic conditions causes ? hydrangeas to change from pink to blue. Organometallic compounds of titanium and this element make up Ziegler Natta catalysts, and this element is the central atom of a hydride is used to reduce esters and carboxylic acids, and is stronger than Sodium borohydride. For 10 points, identify this element which is extracted from bauxite via the Hall Heroult process.
