According to Frank Key's zeta potential web page, a pH range of 6-7 is ideal for dropout. The recommendation is to have it either fairly acid or alkaline for stability. As Roger Altman's calcs on silver ion solubility show, an acid pH is preferable if reasonably high silver ion solubility is desired. The moral seems to be - keep it acid.
