A buffer solution is prepared by mixing 65.5 mL of 0.768 M sodium hydrogen sulfite with 25.3 mL of 0.0706 M sodium sulfite.
Calculate the pH (to two decimal places) of this solution. pKa hydrogen sulfite ion is 7.19
Assume the 5% approximation is valid and that the volumes are additive.
Calculate the pH (to two decimal places) of the buffer solution after the addition of 0.0173 g of sodium sulfite (Na2SO3) to the buffer solution above.
Assume 5% approximation is valid and that the volume of solution does not change.
