Assaying Antimony Determination Method

Assaying Antimony Determination Method. Antimony forms two series of salts, antimonious and antimonic; and advantage is taken of this in its determination volumetrically. Either sulphide of antimony yields antimonious chloride on boiling with hydrochloric acid, sulphuretted hydrogen being given off; and, in the case of antimonic sulphide,......

Iodometric Determination of Copper Cory Home

Pure copper is used as a primary standard for sodium thiosulfate and is recommended when the thiosulfate is to be used for the determination of copper. Upon addition of excess iodide to a solution of Cu(II), a precipitate of CuI is formed along with I 2. The liberated iodine is then titrated with standard sodium thiosulfate. 2 Cu2+ + 4 I2 CuI (s) + I...
