Part A A Beaker With 1 40x10 Ml Of An Acetic Acid Buffer With A Ph Of 5 000 Is Sitting On A Benchtop The Total Molarit 1 (67.23 KiB) Viewed 9 times

Part A A beaker with 1.40x10² mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 4.50 mL of a 0.380 M HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.740. Constants | Periodic Table Express your answer numerically to two decimal places. Use a minus ( - ) sign if the pH has decreased. ▸ View Available Hint(s) Templates Symbols undo redo reset keyboard shortcuts help ApH = 4.71 Submit Previous Answers x Incorrect; Try Again Your answer is the new pH of the buffer solution after the addition of HC1. Compare this value to the initial pH of 5.00 to determine the pH change.
