Problem- A weak monoprotic acid solution of 25.00 mL of an unknown concentration is titrated to the equivalence point with 35.86 mL of 0.08728 M NaOH.
a) Calculate the concentration of the original acid solution. 1:1 solution
ANS: I got 0.1252 M of original acid solution and 3.13.x10-3mol of NaOH
b) At halfway in the titration (50% titrated) the pH of the solution is 6.27. What is the pKa for the acid?
Mention step wise computation of your work done
