It is possible you still had some large particles that had not gotten
broken down with the first drop, but I would guess what you really had
was ionic silver precipitate because it exceeded the solubility limit,
and the second drop converted some of that to 2 atom colloid. Or you
might have had both.
BTW, I was wrong about going up by the 4th power of size, it actually
goes up by the 6th power of size per particle, or 3rd power of size for
a constant ppm.

So after I put in the second drop of H202 this would have made the particles
smaller because I now have a weaker tyndall effect? dee

Since Tyndall only show up on particles, I would expect any sample with similar
ppms to have more tyndall for higher particle concentrations, although particle
size really has much more effect than quantity since the ratio is linear with
concentration, but goes up to the 4th power of size.
