Mohammad Kooti The question mentions TiO2 and you mention TeO2 ('e' and 'i 'are very separate on the keyboard... It may be that the question is badly phrased. Once dissolved (and concentrated hydrochloric acid will do this) then there are just Ti ions and Cl anions. I suspect that the question may relate to dispersion of TiO2 and this is typically not easy if the material is in powdered form. Personally I'd make 30 - 50 nm TiO2 from a sol-gel process. In the sub-100 nm region a suspecion will look as transparent as water. The powdered TiO2's (e.g. P25) typically give a white suspension with a mean size by volume in the 0.3 - 0.35 microns. See attached for some generalities (registration required): Dispersion and nanotechnology https://www.malvernpanalytical.com/en/learn/events-and-training/webinars/W190528DispNanoMat However, the question does mention titanate production and thus solubility would be required.

Sulphuric acid is good solvent for titanium dioxide But it is difficult to perform any reaction in presence of sulphuric acid. so it is better to make suspension of titanium dioxide by adding surfactant which give you better result for further synthesis. or use of nano particle of titanium dioxide is better way.

takeTiO2 in a test tube and add conc HNO3 you will get TiNO3 solution, use the solution as it is for the reaction add a base of NaOH you will get Ti(OH) then heat the product you will get TiO2 back.

TiO2 is not usually soluble in common polar or non-polar solvents. The solubility of titanium dioxide is related to solutes. It is insoluble in dilute alkali, dilute acid, but soluble in hot concentrated sulfuric acid, hydrochloric acid, hydrofluoric acid and nitric acid but not in the form of TiO2 but as a salt like sulfate, chloride, nitrate etc. Titanium dioxide can melt in the alkali (sodium hydroxide, potassium hydroxide) or alkali metal carbonate (sodium carbonate, potassium carbonate). Any one of which i have mentioned with Titanium dioxide can be transformed into soluble acid titanate.

What about the solubility of TiO2 in hot concentrated phosphoric acid？ more easyly dissolve in hot concentrated sulphuric acid or hot concentrated phosphoric acid？ @ Dr. Joy Chakraborty

Dr. Joy Chakraborty I want titanium in nitrate form (TiN) , so can i add HNO3 into TiO2 for getting it.?
