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 sulfate (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 sulfate is equivalent to 0.01543 g of TiCl3.
