A buffer solution is prepared by mixing 43.1 mL of 0.0478 M sodium dihydrogen citrate with 25.5 ml. of 0.273 M sodium hydrogen citrate. table of pKa values can be found here. Calculate the pH (to two decimal places) of this solution. Assume the 5% approximation is valid and that the volumes are additive. Determine the pH (to two decimal places) of a solution prepared by adding 37.0 mL of 0.358 M sodium dihydrogen citrate (NaC3H50(C00H)2C00) to 23.6 g of sodium hydrogen citrate (Na2C3H50(C00H)(C00)2). Assume the volume of the solution does not change and that the 5% approximation is valid. A table of pKa values can be found here. Determine the pH (to two decimal places) of the following solutions. A table of pKa values can be found here. If the 5% approximation is valid, use the assumption to compute pH.
