%X In this paper, we report the comparison between nanosized TiO2 powders prepared via two different acidic conditions (i) pH2 (ii) pH4. The study presents the synthesis of nanosized TiO2 powder with anatase structure was derived from sol-gel process. Data concerning the effect of pH towards the development of TiO2 nanoparticles is reported. The samples were examined by SEM- EDAX, XRD, and FT-IR analysis. Surface morphological studies obtained from SEM micrograph. The Crystalline size of TiO2 powder has obtained for (i) pH 2 is ~3nm (ii) pH 4 is ~ 6nm at 400 oC by controlling the acidity. In FT-IR, all the peaks observed were around 460-560 cm-1 due to stretching and bending vibrations of -OH groups. It was also found the pH of the solution affect the agglomeration of the particles.
