Other possibilities to check. 5. Exposure to light, primarily uv or sunlight. 6. The ph of the CS, upon absorption of CO2 it turns acid, the increased concentration of H+ in the CS causes the particles to NOT repell as well, and thus aggregate. 7 Temperature. High temperatures add increased energy to the particles, thus increasing the chance they will hit each other and aggregate, low temperatures reduce the browning movement, thus allowing increasing concentrations to drift toward the bottom, thus increasing the possibility of aggregation.
