STANDARDIZING OF TITANOUS SOLUTIONS 
369 
SUMMARY 
This paper emphasizes the value of titanous ion in volumetric 
analysis, the iadvantages of the electrometric method for end-points 
in its use, and shows that titanous sulfate solutions may be easily 
and accurately standardized with permanganate or dichromate, 
either directly or through the medium of a ferric-iron solution.
