The sulfate ion concentration in natural water can be determined by measuring the turbidity that results when an excess of bacl2 is added to a measured quantity of the sample. a turbidimeter, the instrument used for this analysis, was calibrated with a series of standard na2so4 solutions. the following data were obtained in the calibration for sulfate concentrations:
