Product description
4. A weighed portion of the drug benzoic acid was placed in a 50 ml flask and made up to the mark with the titration solution. Then 10 ml of the resulting solution was transferred into a 50 ml volumetric flask, brought to the mark with a titration solution and titrated with 0.1 M NaOH. 3.153 ml of NaOH was used for titration. Write a diagram of the quantification process, indicate the indicator, fix the equivalence point. Calculate the titer and weight of the drug sample taken for analysis if the content of the active substance was 96.5%. (The molecular weight of the analyte is 122.12).
