I didn't mean that.
What really forms cloudy matter in silver nitrate solution is
one or more of the chlorination-related compounds, and rarely
other compounds. So, even if the water isn't completely pure,
silver nitrate shouldn't form white participates as long as
chlorinating compounds are absent. So, test for chlorination
is sufficient for this purpose. It was not meant to redefine
Of course, conductivity is one good test. But at the same
time, a lot of waters that fail conductivity test may be
perfectly fine for silver nitrate solution.
