QUESTION 4 For the reaction at 20. °C, NH3(aq) +H(aq) NH4 (aq) The equilibrium constant is calculated to be K - 4.5 x 108 If a base (NaOH) was added to the mixture, the hydroxide ion, OH", would react with the H* to form water. This would decrease the concentration of H* in the solution. How would this affect the concentration of NH4 *? OaThe concentration of NH4* would increase. Ob. The concentration of NH4 would decrease. OCThe concentration of NH4* would remain unchanged.
