A 130.0 mL buffer solution is 0.105 molL−1 in NH3 and 0.135 molL−1 in NH4Br. What mass of HCl will this buffer neutralize before the pH falls below 9.00? (Kb(NH3)=1.8×10−5). If the same volume of the buffer were 0.270 molL−1 in NH3 and 0.400 molL−1 in NH4Br, what mass of HCl could be handled before the pH fell below 9.00.
