Krzysztof Gargul

You need to dissolve TiO2 in concentrated nitric acid to obtain titanium nitrate solution.

TiO2 + 4HNO3 = Ti(NO3)4 + 2H2O

So, to dissolve 79,87 g of pure (100%) TiO2 you need 252,04 g of 100% HNO3 (stoichiometric).

José Antonio Alves Júnior

Try adding a well diluted nitric acid solution and stirring slowly for 4 hours at room temperature.

Shrikaant Kulkarni

The oxidation state of Ti remains +4 in both TiCl4 as well as Ti (NO3)4. You can obtain the later one by making TiO2 and HNO3 in 1:4 molar ratio.
