Precision current with the titration of sodium chlorate as oxidant Iridium
Glass tube to a sealed tube dissolving. Open tube,
stivali ugg, the solution is not concentrated Zhao, transferred to 100ml volumetric flask, ~ 130m, hydrochloric acid, cooled to room Ju, diluted with water to a quiet level, shake. . Accurate extraction 15ml test solution (Pt ~ 25h extraction 10m1) in the 100ml graduated cylinder,
uggs nederland, add 8ml hydrochloric acid,
giubbotti moncler, 5ml1: l sulfuric acid ', diluted with water to 30ml. Following Ibid. Titration, the first rejection pipette add 20. OOmI titer of about 0.22ragIr/ml given ferrous sulfate solution disgrace, and then dump full of micro burette, records titrant volume and the corresponding current value, with titration solution (ml) of the current (cell) mapping requirements end.
