WebJul 17, 2001 · Conventionally, Bi 2 S 3 can be prepared by the direct reaction of bismuth and sulfur vapour in a quartz vessel at high temperatures [5], [6]. The preparation of bismuth sulfide was also reported by thermal decomposition of bismuth dithiocarbamate complexes [7], metal ethylxanthate [8], Bi–thiourea complex [9], or thiosulfatobismuth … WebThe bismuth-thiourea complex has a molar absorption coefficient of 9.32× 103L cm–1mol–1at 470 nm. A 1.00 mL solution containing an unknown amount of bismuth (III) salt (s) was treated with excess thiourea and diluted to a final volume of 10.0 mL, then titrated with 0.50 mL increments of 0.100 mM EDTA solution. Webso the [BiY] 1- is formed and I believe that the titration will be (c) because a complex absorbs and absorbs and then gets to the end point. For the third one the reaction is. Bi (TU)6 3+ + H2Y 2- → [BiY] - + 6TU + 2H +. In my opinion, the [BiY]- and the Bi (III)-TU complex absorb in this case.
