1.2g of a monoprotic acid HA,is titrated with 0.222 M NaOH solution. The pH of the analyte solution is tiration curve is shown in the diagram. The different indicators used in this titratation and their pK_(a) values are as follows : Methyl Red (pK_(a) = 5.8) , Neutral Red (pK_(a) = 7.2), Cresol Purple (pK_(a) = 8.6) How many mL of NaOH is required to bring about the titration to its equivalence point
