RS ISO 760: 1978
Determination of Water — Karl Fischer method (General method)
Abstract

This International Standard specifies a general method
known as the Karl Fischer method[’ I , suitable for the
determination of free water or water of crystallization in
most solid or liquid chemical products, both organic and
SCOPE AND FIELD OF APPLICATION
L inorganic.
Precautions are necessary in certain cases and these are
specified in the appropriate International Standards.
Two methods of titration, depending on whether the endpoint
is detected visually or e!ectrometrically, are specified.
The visual method can be used when no electrometric
apparatus is available but is applicable only to colourless
solutions; it is always a direct titration. The electrometric
method, on the other hand, may involve either a direct
titration or a back-titration. The electrometric method,
whether by direct titration or back-titration, is the more
accurate, and for this reason is recommended.
