Preparation and Standardization of 0.1 M Titanium Trichloride

.

Titanium Trichloride Solution Preparation:

•  Dilute 100 ml of titanium trichloride solution with 200 ml of hydrochloric acid.

•  Add sufficient freshly boiled and cooled water to produce 1000 ml.

Titanium Trichloride Solution Standardization:

•  Standardize the solution immediately before use by titrating with it in an atmosphere of carbon dioxide.

•  Titrate 25 ml of 0.1 M ferric ammonium sulphate (acidified with sulphuric acid) with the 0.1 M Titanium Trichloride solution, using ammonium thiocyanate solution as indicator.

•  1 ml of 0.1 M ferric ammonium sulphate is equivalent to 0.01543 g of TiCl3.
