sompy ayte 3. A turbidimetric determination of sulfate in water was conducted by preparing a series of standard solutions, 0.00, 10.00, 20.00, 30.00 and 40.00 concentration. The solutions were analyzed and obtained transmittance values of 1.00, 0.646, 0.417, 0.269 and 0.174 respectively. Analysis of a 100.00 mL sample of surface water gives a transmittance of 0.538. Calculate the concentration of sulfate in sample. (5)
