State the henderson haselbach equation

Reference no: EM13161117

find the Volume, PH and PKa for (1/4) equivalence point (1/2) equivalence point and at the 3/4 equivalence point. Molarity of NaOH used is 0.05131. 10.0 mL of unknown added to a flask with aprox 40 ml of water. After i titrated the weak acid with the strong base i plotted my point and found the equivalence point to be V=7.82 mL and a ph of 8. SO moles of acid is = to moles of base at equivalence point so moles was determined to be 0.0004012 moles and the molarity of unknown is 0.04012 M unknow acid. I know at 1/2 equivalence point ph=pka bc log 1 =1 for the henderson haselbach equation
