A mixture contains 400.0 mL of 1.00 M NH₃(aq), whose pK_b is 4.76, and 400.0 mLof 1.00 M NH₄Cl(aq). 200.0 mL of 0.0500 M NaOH(aq)were added to the mixture. What was the pH of the mixture before addition of the base and after addition of the base?Hint: Calculate the pH of this buffer solution once before the acid and base are neutralized, and again once after. Organizing your information will be just as important as applying chemistry concepts.
