1. A student wanted to determine the concentration of sulfate by turbidimetry in a 100.0-mL sample of surface water. To be able to find it, he prepared different sulfate standards with the concentrations shown in the Table 1; he then measured the transmittance of each solution via turbidimetry and obtained the results shown in Table 1. Table 1 Concentration of SO, (mg/L) transmittance 0.00 1.00 10.00 0.646 20.00 0.417 30.00 0.269 40.00 0.174 Analysis of the 100.0-mL sample of the surface water gave a transmittance of 0.538. What is the concentration of sulfate in the sample?

Transcribed Image Text:1. A student wanted to determine the concentration of sulfate by turbidimetry in a 100.0-mL
sample of surface water. To be able to find it, he prepared different sulfate standards with
the concentrations shown in the Table 1; he then measured the transmittance of each
solution via turbidimetry and obtained the results shown in Table 1.
