SEPARATION OF MIXTURESConditions and processes involved
SEPARATION OF MIXTURES• SEPARATION OF MIXTURES• There are five types of mixtures. They are:1. Solid-Solid mixture2. Liquid-Liquid mixture3. Solid-Liquid mixture4. Complex mixtureThere are two nature of mixtures generally. They are:1.Homogenous Mixture2.Heterogenous Mixture
SEPARATION OF MIXTURESProcesses of Separation of two Solid-Solid mixtures:1.By Magnetic Separation-This is only possible when one of the component is magnetic. A magnet is placed near the mixture and the magnetic component is separated as separated as shown below:
SEPARATION OF MIXTURES2.By Sublimation- In this process, the solid state of matter directly changes into gaseous state of matter. For this method one component should be sublime and on heating the mixture is separated. The picture below shows the above process:
SEPARATION OF MIXTUREProcesses of separation of two Liquid-Liquid mixtures:1.By Distillation- If the liquid in the mixture are miscible and have different boiling points then they can be separated by distillation. Complete separation is possible if the b.p of the liquid differ by 30 degree C or more.
SEPARATION OF MIXTURES2. By Separating Funnel- If the liquids are miscible then they are put in a separating funnel then it will separate the mixture of two liquids into two distinct layers.
SEPARATION OF MIXTURESProcesses of separation of Solid-Liquid mixture:1.By Filtration- This process is only applicable when solid is insoluble in the liquid and thus forms a heterogeneous mixture. Filter paper is used in this process.
SEPARATION OF MIXTURES2. By Evaporation-This method is suitable when one of the component is a soluble solid and the other a liquid that forms a homogenous solution with that solid component. The liquid can be easily evaporated and its loss can be ignored.
SEPARATION OF THE MIXTURESProcess of separation of Complex mixtures:1.Chromatography-Used mainly to separate color by adsorption and partition.
