3. Extraction. This is the separation of a substance from a mixture by preferentially dissolving that substance in a suitable solvent. By this process a soluble compound is usually separated from an insoluble compound. In its most elementary form this technique involves using a liquid to dissolve a solid to separate it from a mixture.

Jul 24, 2009· Best Answer: Simple distillation is usually used only to separate liquids whose boiling points differ greatly (rule of thumb is >25 °C), or to separate liquids from nonvolatile solids or oils. The greater the difference between the boiling points of two liquids in a mixture the better the separation you can achieve through simple distillation.
Separating Mixtures. For example, if you heat salt water the water in the solution will boil before the salt. The water will then evaporate leaving the salt behind. If the steam from the water is collected it will turn back into liquid as it cools. This cooled water will be pure water without any salt.

Jan 08, 2013· Best Answer: 1. Add H2SO4 to precipitate PbSO4 leaving Cu++ in solution. 2. Same as above leaving Zn++ in solution. 3. Adjust [H+] to 0.3M, add H2S. CuS precipitates, leaving Zn++ in solution. 4. Add HCl to decompose CO3= to CO2., leaving PO4-3 in solution as H3PO4. 5. Add CaCl2(aq) and precipitate CaCO3 ...
Feb 25, 2011· Seperate Sand and Salt mandatory: Salt Sand Water A cooking vessel A range or warm plate test: degree equivalent quantities of salt and sand and then mixture them thoroughly. place the aggregate in a pan and upload water. warmth the water until eventually all of the salt dissolves. enable the sand to settle to the backside of the pan and then pour off the salty water. do away with the sand .
Flotation. The separation depends on the surface properties of the particles and its preference to attach to the gas bubbles. To meet the necessary requirements of the flotation process, a number of additives can be used to control things like the pH of the liquid-solid mixture, the activity of the solid surface,...
Dec 27, 2006· first heat the mixture in a closed container.iodine will sublime and will get cooled on the sides of the container and can be collected from there. then we are left with mixture of salt and sand. add water to it. salt will dissolve and then filter the solution. sand will be left as residue on filter paper. evaporate the solution of salt and water and you will get salt.
Jun 09, 2007· Most later model 2-cycle engines (of any type) usually recommend 50:1 fuel/oil mixture, but the major thing to remember is to use a 2-cycle oil that''s rated at 50:1 because using any lesser rated oil will ruin the engine.

Separation of Mixtures Using Different Techniques A system of material which comprises of two or more different substances mixed together but are not chemically combined is known as a mixture. Mixture is defined as a physical combination of two or more substances whose identities are retained.
Conclusion: This lab dealt with the separation of components of a mixture. The purpose of the lab is to become familiar with the methods of separating substances from one another using decantation, extraction, and sublimation techniques. Mixtures occur in everyday life in materials that are not uniform in composition. These mixtures are said to be impure or heterogeneous.
