Another approach utilizes titrimetry, where a standard solution of a titrant, such as lead perchlorate or barium perchlorate, is used to react with the sulfate ions. The endpoint of the titration is determined either by a color change indicator or more sophisticated instrumentation like a potentiometric titrator The endpoint of the titration is determined either by a color change indicator or more sophisticated instrumentation like a potentiometric titrator The endpoint of the titration is determined either by a color change indicator or more sophisticated instrumentation like a potentiometric titrator The endpoint of the titration is determined either by a color change indicator or more sophisticated instrumentation like a potentiometric titratordetermination of sulphate as tio2. The volume of titrant used corresponds to the concentration of sulfate in the sample. Again, a stoichiometric calculation converts this to TiO2 content.

To make up the batch of lithopone the solution containing the original 1050 pounds of barium sulphide and 856 pounds of titanium acid cake is added to sufiicient zinc sulphate solution of approximately 35 Baum at 60 Centigrade to completely precipitate all the BaS as zinc sulphide and barium sulphate so that the final precipitate contains a suspen-. sion of co-p'recipitated zinc sulphide barium sulphate intimately mixed with a suspension of titanium oxide. On the completion of the reaction, shown by the complete absence of either soluble zinc or barium in a filtered por-.
