3. 1.00 dm3 of waste water containing nickel was evaporated to dryness and after separation of impurities a precipitate of nickel dimethylglyoximate was obtained. The washed precipitate was dissolved, 10.00 cm3 of a 0.010 M solution of complexone III was added, 3.05 cm3 of a 0.010 M solution of a magnesium salt was spent to titrate the excess of the latter. Calculate the mass concentration of nickel (mg / dm3) c. waste water
