You add 1 mol of acetic acid (pka 4.76) and 0.5 mol of NaOH to 1 L of water. Find the pH of the solution.

Expert Solution

CH3COOH + NaOH -------------> CH3COOH

I 1 0.5 0

C -0.5 -0.5 +0.5

E 0.5 0 0.5

[CH3COOH] = 0.5M

[CH3COONa] = 0.5M

PKa = 4.76

PH = PKa + log[CH3COONa]/[CH3COOH]

= 4.76 + log0.5/0.5

= 4.76 + 0

= 4.76 >>>>answer

Draw a graph of the relationship of the % ionization of acetic acid (pK – 4.76)...

Draw a graph of the relationship of the % ionization of acetic acid (pK – 4.76) and pH. Use the following pH values to calculate % ionization ( 3.06, 3.76, 3.86, 3.96, 4.06, 4.16, 4.26, 4.76, 4.86, 5.16, 5.56, 5.76, 6.66). *Graph is not necessary, I can do that. Just need help finding one or two of the different answers with the different pH values
