49. Solution to Chemistry Problem
101. Based on the results of measurements of the specific electrical conductivity (ae) of the treated wastewater of the Baikal Pulp and Paper Mill and the values of the concentrations of dry substances contained in it:
Cdry substance, mg/dm3 510 515 520 530 540 550 560 570 580
ae, μS/cm 836 844 852 869 885 902 918 934 951
plot a calibration graph and determine the concentration of dry substances (mg/dm3) in the analyzed sample, the electrical conductivity of which is 890 μS/cm, provided that all electrical conductivity measurements were carried out under the same conditions on a conductometer with automatic temperature compensation.
