What ratio of concentration of ammonia and ammonium chloride should be mixed to prepare a buffer solution of pOH 5? (Kb for NH3 = 1.8 x 10^-4)
Added by Cesar S.
Step 1
In this case, the weak base is ammonia (NH3) and its conjugate acid is ammonium chloride (NH4Cl). The pOH of the solution is given as 5. We know that pOH + pH = 14, so the pH of the solution is 14 - 5 = 9. We also know that the Kb (base ionization constant) for Show more…
