Potassium Permanganate. Recrystallised salt, supplied from the Chemical 

 Laboratory, was dissolved ; 5'3370 grammes in 198'42 grammes of solution. 



Solution (a) had, therefore, a concentration of 1746 X 10~* gramme-equivalent' 

 per gramme of solution. 



Two other solutions were prepared from this, having respectively concentrations of 

 4 '255 X 10~ 5 and . r >'014 X 10~ gramme-equivalent per gramme of solution.
