Titration can be used to quantitatively determine an unknown compound. In this experiment, a standardized sodium hydroxide solution was used to titrate an unknown weak acid and therefore determine the pKaÂ and molar mass of that acid. The experiment was carried out according to laboratory manual number EQUL0857 and the data obtained was processed by drawing titration and first derivative graphs. The pKaÂ values obtained were 2.55 and 2.59 while the molar mass values were 132.35g and 138.78g. The big difference between each pair of values was associated with experimental errors.
