6. A weighed portion of the drug Verapamil was placed in a 50 ml flask, and brought to the mark with a titration solution. Then 25 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 HClO4. Calculate how many ml of HClO4 was spent on titration if the content of the analyte in the sample turned out to be 100%. Write a diagram of the quantification process, indicate the indicator, fix the equivalence point. (The molecular weight of the analyte is 454.61).
