Answer :
We can find out H3o+, oH ph and pOH. The H+ of HCl (a strong acid) reacts with the base member of the buffer [CH3COO−]. Thus, [CH3COO−] decreases and [CH3COOH] increases. Calculating the pH of a buffer after addition of a strong acid or robust base.
The first-rate buffers have about equal quantities of every conjugate: [CH3COOH] ≈ [CH3COO-], to withstand sturdy acid and sturdy base equally. Example: 1.0 L of a buffer solution contains 0.10 moles of CH3COOH and 0.080 moles of NaCH3COO.
What is the pH of 0.50 M acetic acid ?
Therefore, the pH of 0.5 M acetic acid is 2.52.
