Abstract: Heteromolecular homogeneous nucleation of sulphuric acid (H2SO4) has been considered for different mass fractions as the function of number of water molecules as well as H2SO4 molecules. T he calculations have been made for critical radius, free energy of formation of critical nucleus as the function of weight percentage of H2SO4. The calculated values have been compared with those for HCl and HNO3. The pH values of solution of H2SO4 and H2O have been calculated. The results show that pH of H2SO4 solution decreases with the decrease in water molecules for a given value of H2SO4 molecules. It has also been inferred that the pH has positive values for weight percentage of H2SO4 < 10, while it is negative for weight percentages ≥ 10.
