Question:
Silica particles with a diameter of 400 nm were measured to have a zeta potential of -60 mV in water. A stable suspension of 2 wt% of these silica particles was flocculated by adding a negatively charged polymer, a polyelectrolyte: Polystyrene Sulfonate. The concentration of the polymer was 10,000 parts per million (ppm).
What interaction force caused the particles to flocculate? Name one simple step to resuspend the flocculated particles.
