Re: Measuring the color and absorbency of sols.
"If the particle size is so small as to not transmit a color, how would a
colorimeter possibly be used to accurately determine concentration? There
is a direct contradiction here."
You react the Ag with substance(s) which create another compound in

### Ah, that clears up a lot of questions and makes sense. There was a
fellow from a water softener company that came by here to test my well
water. He used a process similar to what you describe and compared the
results to a set of color charts.
