A buffer is prepared by mixing 41.2 g of NH3 and 41.2 g of NH4Cl in 0.335 L of solution. What is the pH of this buffer, and what will the pH change to if 7.65 g of HCI is then added to the mixture? Your answer is correct. pH of this buffer= 9.83 eTextbook and Media Hint * Your answer is incorrect. The pH change- i -0.557315 (in case of decreasing pH the answer should be negative).
