Vanadyl sulfate (VOSO4, FM 163.00), as supplied commercially, is contaminated with H2SO4
Chapter 25, Problem 25-A(choose chapter or problem)
Vanadyl sulfate (VOSO4, FM 163.00), as supplied commercially, is contaminated with H2SO4 (FM 98.08) and H2O. A solution was prepared by dissolving 0.244 7 g of impure VOSO4 in 50.0 mL of water. Spectrophotometric analysis indicated that the concentration of the blue VO2 ion was 0.024 3 M. A 5.00-mL sample was passed through a cation-exchange column loaded with H. When VO2 from the 5.00-mL sample became bound to the column, the H released required 13.03 mL of 0.022 74 M NaOH for titration. Find the weight percent of each component (VOSO4, H2SO4, and H2O) in the vanadyl sulfate. 25-
