Compute the equivalent weight of the unknown weak acid

Reference no: EM13165381

It requires 19.58 mL of NaOH solution to titrate 0.4307 g of the primary standard KHP (MW=204.23g/mol). It requires 16.00 mL of the same NaOH solution to titrate 0.1147 g of an unknown weak acid dissolved in 100.0 mL of water. From the titration curve, the acid appears to be diprotic with pKa1= 2.56 and pKa2=4.37.

a)Calculate the equivalent weight of the unknown weak acid (g/eq).

b)Calculate the molecular weight of the acid described in Question (g/mol).

c)Calculate the pH of the weak acid solution described in Question at the point whereonly 5.00 mL of NaOH have been added.

d)Calculate the pH of the solution desribed in Question at the second equivalence point.
