A 1.00 liter solution contains 0.38M nitrous acid and 0.49M potassium nitrite. If 0.25 moles of sodium 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 sodium hydroxide.) A. The number of moles of HNO2 will increase. B. The number of moles of NO2will increase. C. The equilibrium concentration of H3O+will increase. D. The pH will remain the same. E. The ratio of [NO2][HNO2] will decrease
