Step 1
76 \] \[ [CH_3COO^-] = 0.005 M \] \[ [CH_3COOH] = 0.025 M \] Substitute the values into the equation: \[ pH = 4.76 + \log\left(\frac{0.005}{0.025}\right) \] \[ pH = 4.76 + \log(0.2) \] \[ pH = 4.76 + (-0.69897) \] \[ pH = 4.06103 \] ** Show more…

You titrate 100 mL of an old batch of vinegar with 0.1 M NaOH. Using your titration curve below determine the pKa of acetic acid (CH3COOH) and the concentration of acetic acid present in the sample.

What is the maximum volume of 2.1 M NaOH(aq) that the buffer (pH=5.75) prepared from sodium acetate and 2.5 L of 0.55 M acetic acid can tolerate without showing a pH change greater than 0.25 units? pKa of acetic acid is 4.75.

Below is the titration curve of a weak acid and strong base. Indicate the region of the graph affected by buffering action. Locate and mark the location along with pH value where the acetic acid and the acetate ions concentration are approximately equal. Explain why the pH at the equivalence point is not 7. pH Equivalence point Volume NaOH added (mL) The pH titration curve of weak acid (CH3COOH) and strong base (NaOH)
