Kako izračunati Colloid
Kaj je Colloid?
Colloid properties: suspensions of 1 nm-1 μm particles; colloidal stability depends on pH, ionic strength, surface charge.

Oil-in-water emulsion: stability improved by surfactants reducing interfacial tension
Rezultat
Surfactant concentration critical
Common Mistakes to Avoid
- ✕Neglecting DLVO interactions
- ✕Not accounting for pH effects on charge
Frequently Asked Questions
Why are colloids kinetically stable?
Brownian motion prevents settling; particles too small for gravity, too fast for diffusion aggregation.
