A 1.00-litre buffer solution is made up containing 0.100 mol acetic acid and 0.200 mol sodium acetate: what is its’ pH? Then, 0.0500 mol of HCl gas is bubbled into the solution (assume no change in volume): what is the new pH? Data: pKa for acetic acid = 4.76
Suppose you are given solutions of 1.00 M acetic acid and 1.00 M sodium acetate and are asked to make 100.00 mL of buffer at pH 5.00 using only these two solutions. What volume, in milliliters, of acid would you need? The pKa of acetic acid is 4.75
Your task is to prepare a buffer solution of 1.00 L of 0.250 M acetic acid and solid sodium hydroxide. Start by writing the equation for the reaction that will form the buffer (hint: you must have both acetic acid and acetate ion in the solution; where will the acetate ion come from? Neglecting the volume change on addition of NaOH (MM 40.0 g/mol), what mass is required to produce a buffer of pH 3.75? What pH will the buffer...
4. How much of (in mL) 0.15 M acetic acid (pKa 4.76) is needed to mix with 40 mL of 0.15 M sodium acetate to make a buffer of pH = 4.50 of 250 mL? (molar mass of acetic acid and sodium acetate are 60.0 g/mol and 82.0 g/ml, pKa of acetic acid is 4.76) (extra 10 pt)
