The total molarity ofacid and conjugate base in this buffer is 0.100 mol LI. A student adds 8.00 mL of a 0.430 mol L- HCI solution toStudy Areathe beaker. How much will the pH change? The pha of acetic acid is 4.760.Express your answer numerically to two decimal places. Use a minus ( – ) sign if the pH has decreased.User SettingsDView Available Hint(s)AEQ?ApH =SubmitProvide FeedbackNext >PearsonCopyright @ 2019 Pearson Education Inc.
