1. What is the rate of coagulation of naturally occurring colloids (under various pH and I scenarios)? G p gg 2. How might the size spectrum of agglomerates change over time? 3. How quickly do colloidal aggregates settle? How far might they travel? How might the composition of colloidal aggregates in sediments vary as a function of distance? Y in what sequence might various colloids with different stability constants settle out (how wide is the transition zone)?
