(1)TiCl4+H2O=TiOCl2(由[TiO]2+和Cl-组成)+2HCl
(2)Zn+8HCl(浓)+2TiCl4=2H3[TlCl6]+H2[ZnCl4]
H3[TiCl6]+6NaOH=6NaCl+3H2O+Ti(OH)3↓
(3)3Ti(OH)3+7HNO3=3TiO(NO3)2+NO+8H2O(3价的Ti又被氧化成4价)
(或写成3Ti(OH)3+13HNO3=3Ti(NO3)4+NO+11H2O,但上一个更科学)
TiO(NO3)2+2NaOH+H2O=Ti(OH)4+2NaNO3
(或写成Ti(NO3)4+4NaOH=Ti(OH)4↓+4NaNO3)
(4)Ti(OH)4(加热)=TiO2+2H2O
MgO+TiO2(高温)=MgTiO3(偏钛酸镁)
