15. Solving a chemistry problem

30. Give the reaction equations for the quantitative determination of glutamic acid (Mg 147.13) in tablets by alkalimetry.
A. Calculate the molar mass of the equivalent, the titer for the analyte, a weighed portion of the powder of crushed tablets of glutamic acid, 0.25 g each, so that 10 ml of 0.1 mol/l sodium hydroxide solution (K = 0.99) is used for titration. The weight of one tablet is 0.503 g.
b. Calculate the content of glutamic acid in one tablet, if 16.6 ml of 0.1 mol/l sodium hydroxide solution (K = 1.02) was used to titrate the powder of one crushed tablet.
