PPT-Electric Properties Of Colloids

Particles dispersed in liquid media may become charged mainly in one of two ways The first involve selective adsorption of a particular ionic species present in solution Second charges on particles arises from ionization of groups such as COOH that may be situated at the surface of the particles. Ensure the ultimate safety of your horses, cattle, sheep, livestock, dogs, and other pets with high tensile fence or other electric fencing. Our farm fencing accessories and electric horse fence supplies are also ideal for deterring predators, deer, and other garden pests. Ranchers, farmers, and other horse owners know how important a safe environment is to raising horses. While it is essential to keep horses within the boundaries of your property and safe from would-be predators, these valuable animals can easily be injured by fence railing that cracks or splinters. We offer the widest selection of horse fencing, electric fences, polytapes, energizers, polyrope, fencing accessories and other equine products.

An . electric bicycle. , also known as an . e-bike.  or . booster bike. , is a bicycle with an integrated electric motor which can be used for propulsion. . There is a great variety of e-bikes available worldwide, from e-bikes that only have a small motor to assist the rider's pedal-power to somewhat more powerful e-bikes which tend closer to moped-style functionality.. DR AMINA TARIQ. BIOCHEMISTRY. COLLOIDAL STATE. Colloids are a type of mixture. It is composed of two phases: . Dispersion medium and dispersed phase.. Colloids are the mixtures in which dispersion . phase. Colloids and suspensions are heterogeneous . mixtures. Suspensions and Colloids. Suspensions and colloids are NOT solutions. . Suspensions. : The particles are so large that they settle out of the solvent if not constantly stirred.. Suspensions:. Heterogeneous mixtures. Relatively large particles. e.g. whole blood. many medicines (Shake well before using). Classes of solutions. True Solutions. (Suspensions). Colloidal Solutions. Anaesthetic. Practice. G . Ogweno.

Charges are conserved. Charges are additive in nature. Charges are quantised.. PROPERTIES OF ELECTRIC CHARGES. PRODUCTION OF ELECTRIC CHARGE. We can get electric charge by three ways. By friction or rubbing.
