Simultaneous determination of ti and v. determine the % of each if 1.000 g of a steel was dissolved and diluted to 50.00 ml; spectrophotometric analysis produced an absorbance of 0.172 at 400 nm and 0.116 at 460 nm. two separate solutions were also analyzed; the first solution which contained ti (1.00 mg/50.00 ml), gave an absorbance of 0.269 at 400 nm and 0.134 at 460 nm. the second solution contained v( 1.00 mg/50.00 ml) and gave an absorbance of 0.057 at 400 nm and 0.091 at 460 nm.
