A possibility:
Since adding H2O2 to ionic silver water after a while doesn't oxidize
the ions like doing that too soon does, they must also be hiding out from
the meter as well as the H2O2.
Given that the anion OH [-] is produced at a 1 to 1 ratio with the Ag [+]
ions and also are conductive [accounting for half the total conductivity in
fresh EIS] , it stands to reason that the meter is seeing those and not the
hiding silver [in stabilized EIS]...and that would account for the
conductivity drop at around 40%, given other low solubility limits of other
byproducts such as silver oxide and hydroxide handing around 10% of the
high end of a possible Ag [+] 'Hide out" at 50% drop, back.
ie:
Reading stabilized EIS...
Silver ions ~zero
OH anions ~ 35-50%
Other products around 3-15%, some portion of that as OH compounds with Ag
that didn't get away, in solution and some soluble Oxides.
Thus, 1 uS = ~ 1 PPM "OH" AFTER the conductivity stops dropping....and
the OH is fairly equal to the Ag with however much was used up making
insoluble AgOH as a variable deduction with the small soluble portion of
AgOH contributing.
Concept Simplified: You aren't even measuring the "silver ions"..it's
their mirror image anions you see...along with a few "groupies" counting
into the crowd.

The ppm of the silver does not change with aging, it simply has some
convert from ionic to colloidal component, and the meter only reads the
ionic portion.

If your CS reads 8 on the TDS (as mine does) this will mean the ppm is
approximately 16ppm. This generally drops to 5 after a few days which
means the finished ppm is approximately 10ppm. dee

Too many answers and technical stuff.
So by example , can someone please tell me.
I have cs , u/s reading of 14.
What will the approx. cs ppm be?
Is 7ppm the correct answer?
Thanks all...nessie

It's 1 to 1 TDS readings are 1/2 the PPM
