A 1.00 liter solution contains 0.46 M nitrous acid and 0.60 M sodium nitrite. If 0.15 moles of barium hydroxide are added to this system, indicate whether the following statements are true or false. (Assume that the volume does not change upon the addition of barium hydroxide.) A. The number of moles of HNO2 will increase. B. The number of moles of NO₂ will increase. C. The equilibrium concentration of H3O+ will decrease. D. The pH will remain the same. E. The ratio of [HNO2] [NO2] will decrease. When a 16.4 mL sample of a 0.475 M aqueous acetic acid solution is titrated with a 0.301 M aqueous sodium hydroxide solution, what is the pH at the midpoint in the titration? pH = 4.85
