What will be the pH of a buffer solution prepared from 0.20 mol acetic acid (CH3COOH), 0.45 mol sodium acetate (CH3COONa), and just enough water to give 1.00 L of solution? The Ka for acetic acid is 1.75 x 10-5.

Step 1
First, we need to find the concentration of acetic acid and sodium acetate in the solution. Since the solution has a volume of 1.00 L, we can directly use the moles to find the concentration. [CH3COOH] = 0.20 mol / 1.00 L = 0.20 M [CH3COONa] = 0.45 mol / Show more…

You have prepared a buffer solution by adding 0.50 mole of acetic acid (pKa = 4.75) and 2.5 moles of sodium acetate to enough pure water to make 1.0 liter of solution. What is the pH of the buffer?
