(Assume that the volume does not change upon the addition of barium hydroxide.) A. The number of moles of NH3 will increase. B. The number of moles of NH4 will decrease. C. The equilibrium concentration of H3O will remain the same. D. The pH will decrease. E. The ratio of [NH3] / [NH4 ] will increase.
