Question

A 1.00 mL aliquot of a hydrogen peroxide (H₂O₂) solution was added to 2.00 mL of acidified Ti(IV) solution and the solution was transferred to a 1.00 mm cuvette. The absorbance of the solution against a matched reference cuvette containing Ti(IV) solution only was 0.250 at 410 nm.

Determine the concentration of the H₂O₂ solution in mol dm^–3 given that the molar absorptivity coefficient for the Ti(IV)–H₂O₂ complex is 770 dm³ mol^–1 cm^–1.
Assuming the density of the H₂O₂ solution is 1.00 g mL^–1, determine the concentration of

the H₂O₂ solution as a %(w/w).
