|Origin of Name||After the Titans, sons of the Earth goddess.|
|Discovery Credits||Rev. W. Gregor at Creed, Cornwall, UK and later by M. H. Klaproth in 1795 at Berlin, Germany.|
|Standard State||Solid at 77 F & 298 K|
|Description||Hard, lustrous, silvery metal. Resists corrosion due to oxide layer, but powdered metal burns in air. Unaffected by many acids, (except HF,
H3PO4, and concentrated H2SO4) and alkalis. White
TiO2 used in paints. Metal used in chemical plants, lightweight alloys, hp replacement joints, etc.
A). Titanium oxides, dissolved in the Na2(NH4)(PO4) bead, gives a glass that is yellow when hot and colorless when cold in the oxidizing flame. In the reducing flame the bead color is yellow when hot and a delicate violet color when cold. These bead tests are easily interfered with from other elements such as iron and manganese.
B). After fusing the mineral with powdered Na2CO3, dissolve the bead in HCl acid which produces a solution of Ti4+. If this solution is boiled with granulated Tin, Ti3+ is produced which gives the solution a delicate violet color.
C). After fusing the mineral with powdered Na2CO3, dissolve the bead in 1cc H2SO4 acid and 1 cc water. Heat the solution until it becomes clear. When cold, add 1cc 20% H2O2 to the mixture, if titanium is present, the solution becomes reddish-yellow to deep amber, depending on the quantity.
