Question 8 (2 points) A 1.00-L of a buffer contains 0.076 M CH3COOH(aq) and 0.214 M CH3COONa(aq); Kalacetic acid) - 1.8 x 10-5. Calculate the pH after the addition of 0.003 moles HCI. Provide your answer to two places after the decimal.
A buffer solution that is 0.482 M in CH3COOH and 0.482 M in CH3COONa has a pH of 4.74. The addition of 0.01 mol of H, 07 to 1.0 L of this buffer would cause the pH to The capacity of this buffer for added OH could be increased by the addition of 0.185 mol [Review Topics [References] Use the References to access important values if needed for this question.
