a. Colloidal particles typically have a negative surface charge that attracts oppositely charged positive ions in the surrounding bulk solution. These so-called _______-ions are held at the particle surface through electrostatic and van der Waals forces of attraction strongly enough to overcome thermal agitation. b. Turbine and propeller type mechanical mixers used for rapid mixing of reagent chemicals have either ------------- flow impellers with flat or curved blades located parallel to the axis of the drive shaft, or --------------------- flow impellers with blades making an angle of less than 90o wit
