3.743 g of a weak monoprotic acid, HA was dissolved in water to a volume of 250 mL in a volumetric flask. Then 25.0 mL of this solution was titrated with KOH solution where 16.0 mL of 0.192MKOH was required to neutralize it. a) State the approximate pH at the equivalence point of the titration and give your reason. (2 marks) b) Suggest a suitable indicator and state its colour change at the end point. (2 marks) c) Give the chemical equation of the reaction involved in the titration. (1 mark) d) Calculate the molecular weight of HA. (5 marks)
