Titanium sulphate, reagent

We are now going to investigate the behavior of a number of oxides with acids and we are going to use the titanium sulphate reagent to discover whether or not hydrogen peroxide is formed by the action.

Titanium sulphate reagent Digest 1 g of anhydrous titanium dioxide with 100 ml of concentrated sulphuric acid for fifteen to sixteen hours on a sand-bath at 150. Cool, dilute with four parts by volume of water and centrifuge to obtain a clear solution. 

Reactions of titanium(IV) ions To study these reactions use a 0-2m solution of titanium(IV) sulphate, which is prepared either by dissolving the reagent [Ti(S04)2] in 5 per cent sulphuric acid, or by fusing titanium dioxide TiOz with a 12—15 fold excess of potassium pyrosulphate in a porcelain or platinum crucible.
