A 2.036 g of copper (II) salt was dissolved in a 250 mL volumetric flask. A 25 mL aliquot of the solution was analyzed by adding 1 g of potassium iodide and titrating the liberated iodine with 24.45 mL of 0.1664 M of sodium thiosulfate. Determine the percent by weight Cu in the sample. Cu²+ + Cul(s) + 13 13 + S2O3²- →|-+S406²- 19.05% O 12.70% O 6.35% 25.40%
