Methods of separating mixtures. • Methods of drying solids. • Methods of determining purity of solids and liquids. LEARNING OBJECTIVES Students should be able to: ➢ Define the key terms such as solution‚ solvent‚ solute‚ filtrate‚ residue‚ immiscible and miscible liquids‚ distillate‚ sublimation‚ melting and boiling points and chromatography. ➢ Use melting and boiling points to differentiate between pure and impure substances. ➢ Select appropriate methods for separating given

Available evidence suggests that tef grain separating and cleaning‚ in the rural area of Ethiopia‚ is very much traditional and makes use of wind as winnower to effect separation manually operated set of flat sieve to accomplish the cleaning. This method is time and labor consuming‚ and often lead to contamination of the tef grain with dust‚ dirt‚ small sands or silt on the threshing ground. In an effort to alleviate the above stated problems‚ a small engine driven tef grain and chaff separator and

strategy‚ we say it is a pooling equilibrium; if they differ‚ we say it is a separating equilibrium); one type of Player 1 may play a pure strategy while the other plays a mixed strategy (leading to a semi-separating equilibrium); or both types of Player 1 may play mixed strategies. (We won’t deal with the latter case.) When looking for a PBE... 1. Decide whether you’re looking for a separating‚ pooling‚ or semi-separating equilibrium. 2. Assign a strategy (a message for each type) to Player 1; make

EXPERIMENT 13： Extraction: Extraction with acid and alkali Objective 1. To recover the benzoic acid and p-dichlorobenzene from its mixture from its mixture by using acid-alkali extraction. 2. To determine the percentage recovery and melting point of the recovered benzoic acid and p-dichlorobenzene. Introduction Acid-base extraction is a process which purifying the acids and bases from mixtures based on their chemical properties. Acid-base extraction is performed to isolate the compounds and natural

meaningless to us. Separating mixtures is extremely important to human lives; for example‚ many people filter water so that it is safe for drinking. Mixtures contain two or more substances that are not in a fixed ratio‚ and while some mixtures‚ such as concrete‚ are useful‚ others including salt water‚ are not as useful to us. Filtration‚ distillation‚ paper chromatography‚ and centrifugation are just a few methods used for separating mixtures. There are many methods of separating mixtures. A more
