A buffered solution was created by mixing solutions of NH4Cl and NH3 at 25 C. Which species, NH4+ or NH3, has the highest concentration in this buffered solution?. Justify your answer.

Answer 1

This question can't be answered without know the pH of the solution. If you know the pH of the solution, substitute it into the Henderson-Hasselbalch equation and solve for the ratio of base to conjugate acid.
