A 1.00 liter solution contains 0.40 moles nitrous acid and 0.31 moles potassium nitrite. If 0.15 moles of hydrobromic acid 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 hydrobromic acid.) DA. The number of moles of HNO, will increase. B. The number of moles of NO, will increase C. The equilibrium concentration of H,0″ will increase D. The pH will decrease. E. The ratio of [HNO,]/[NO2] will remain the same.
