Titanium and vanadium form colored complexes when treated with hydrogen peroxide in 1 M sulfuric acid. The titanium complex has an absorption maximum at 415 nm, and the vanadium complex has an absorption maximum at 455 nm. A 1.00 × 10−3 M solution of the titanium complex exhibits absorbance of 0.816 at 415 nm and of 0.485 at 455 nm while a 2.00 × 10−3 M solution of the vanadium complex exhibits absorbances of 0.425 and 0.608 at 415 and 455 nm, respectively. A 1.000-g sample of an alloy containing titanium and vanadium was dissolved, treated with excess hydrogen peroxide, and diluted to a final volume of 1000 mL. The absorbance of the solution was 0.697 at 415 nm and 0.533 at 455nm. Calculate: a) The concentration of titanium and vanadium in the sample. b) The percentages of titanium and vanadium in the alloy

Titanium and vanadium form colored complexes when treated with hydrogen peroxide in 1 M sulfuric acid. The titanium complex has an absorption maximum at 415 nm, and the vanadium complex has an absorption maximum at 455 nm. A 1.00 × 10−3 M solution of
the titanium complex exhibits absorbance of 0.816 at 415 nm and of 0.485 at 455 nm while a 2.00 × 10−3 M solution of the vanadium complex exhibits absorbances of 0.425 and 0.608 at 415 and 455 nm, respectively. A 1.000-g sample of an alloy containing titanium and vanadium was dissolved, treated with excess hydrogen peroxide, and diluted to a final
volume of 1000 mL. The absorbance of the solution was 0.697 at 415 nm and 0.533 at 455nm. Calculate:
a) The concentration of titanium and vanadium in the sample.
b) The percentages of titanium and vanadium in the alloy.
