The standard additions method was used to determine nitrite in a soil sample A 1 00 mL portion of the sample was mixed with 24 00 mL of a colorimetric reagent and the nitrite was converted to a colored product that produced an absorbance of 0 300 To 50 mL of the original sample 1 00 mL of a standard 1 00 x 10 3 M nitrite solution was added The same color formation procedure was carried out and the absorbance obtained was 0 530 What was the nitrite concentration in the original undiluted sample
