Titanium(IV) and vanadium(V) 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 × 103 M solution of the titanium complex exhibits an absorbance of 0.805 at 415 nm and of 0.465 at 455 nm, while a 1.00 x 10-2 M solution of the vanadium complex exhibits absorbances of 0.400 and 0.600 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 100 mL. The absorbance of the solution was 0.685 at 415nm and 0.513 at 455nm. What were the percentages of titanium and vanadium in the alloy?

Question
Transcribed Image Text:Titanium(IV) and vanadium(V) 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 x 103 M solution of the titanium complex exhibits an
absorbance of 0.805 at 415 nm and of 0.465 at 455 nm, while a 1.00 x 10-2 M solution of the vanadium
complex exhibits absorbances of 0.400 and 0.600 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 100 mL. The absorbance of the solution was 0.685 at 415nm and 0.513 at
455nm. What were the percentages of titanium and vanadium in the alloy?
