Abstract
The acidimetric titration of sulfamic acid with electrogenerated hydro xide ions was studied. The accuracy of the method was determined by ex amining the dependencies on the storage time of sulfamic acid solution , amount of sulfamic acid, etc.; the precision and accuracy obtained w ere 0.01%. The coulometric titration of sulfamic acid was compared wit h that of potassium hydrogenphthalate. To determine the effect of carb on dioxide, examining the dependence on sample amount is recommended.
