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
