Transcribed Image Text:

The simultaneous determination of titanium and vanadium, each as their peroxide complex, can be done in steel. Preliminary measurements indicated that 1.00 mg of pure Ti in 50 mL with H₂O2 gave an absorbance of 0.269 at 400 nm and 0.134 at 460 nm in a 1.00-cm cell. Under similar conditions, 1.00 mg of pure V in 50 mL gave an absorbance of 0.057 at 400 nm and 0.091 at 460 nm. For a 1.000-g steel sample treated with H₂O2 and ultimately diluted to 50 mL, the absorbance at 400 nm was 0.172 and that at 460 nm was 0.116 in the same 1.00-cm cell. Calculate the percent of titanium and vanadium from these absorbance values. The simultaneous determination of titanium and vanadium, each as their peroxide complex, can be done in steel.
