54. Solving a chemistry problem

11. The control and analytical laboratory received the dosage form:
Tabulettae Vikasoli 0.015
a) Give the structural formula, chemical and Latin name of vikasol. Label the functional groups.
b) Give all possible reactions of vikasol identification.
c) Give the reaction for the quantitative determination of vikasol by the cerimetry method, the indicator used, the method of fixing the equivalence point.
Calculate the mass of the sample if 4.3 ml of a 0.1 N solution of cerium sulfate was used for its titration. Mr mendralon sodium bisulfate = 330.29. The average weight of tablets is 0.108.
