Use the Henderson-Hasselbalch equation to perform the following calculations. The Ka of acetic acid is 1.8 10-5. Calculate the volume of the 0.
Use the Henderson-Hasselbalch equation to perform the following calculations. The Ka of acetic acid is 1.8 × 10–5.a. Calculate the volume of the 0.500 M acetic acid and the volume of deionized water necessary to make 60.0mL of 0.250 M CH3COOH.b. Buffer: Calculate the mass of solid sodium acetate required to mix with 60.0 mL of 0.250 M acetic acid toprepare a pH 4 buffer. Record the mass in your data table.
1) Calculate moles of 0.250 M CH3COOHM = m/V0.250 = m /0.06 LM = 0.250 * 0.06 = 0.015 moleCalculate volume of 0.5 M CH3COOHV = m/MV = 0.015/0.5V = 0.03 L V = 30 mlPh = PKa +...
