42. Solving a chemistry problem

33. A weighed portion of the drug Acetylsalicylic acid weighing 0.1998 was placed in a 25 ml flask and brought to the mark with a titration solution. Then 5 ml of the obtained solution was transferred into a 50 ml volumetric flask, brought to the mark with titration solution and titrated with 0.1 M NaOH. 2.075 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 content of the active substance in the sample. (The molecular weight of the analyte is 180.2).
