It is defined as the separation process in which two immiscible liquids are separated. This is done by pouring out the clear upper layer of liquid. Separation of a mixture of oil from water is an example of decantation. Example.

Decantation involves separating a liquid from a solid by pouring the liquid, called the supernate, from the mixture without disturbing the solid residue. Filtration involves pouring a solid-liquid mixture (suspension) through a piece of filter paper or other porous material to separate the solid from the liquid.

Decantation is a method which follows sedimentation. Once the solid has completely settled down, the clear liquid above is poured out leaving behind the insoluble heavy solid particles. Filtration on the other hand is a more sophisticated approach of separation of a solid and liquid.

Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. Example sand from water can be separated by decantation.

Decantation can be used to separate immiscible liquids that have different densities. For example, when a mixture of water and oil is present in a beaker, a distinct layer between the two consistency is formed, with the oil layer floating on top of the water layer.

Separating immiscible liquids is done simply using a separating funnel. The two liquids are put into the funnel and are left for a short time to settle out and form two layers. The tap of the funnel is opened and the bottom liquid is allowed to run. The two liquids are now separate.

Two immiscible liquids, oil and water, can be separated by using Separating Funnel. The mixture of oil and water forms two separate layers because they are completely insoluble in each other.

Principle of Distillation This method is used to separate a mixture of solid into a liquid. It is used to separate components of a mixture containing two miscible liquids that boil without decomposition and have sufficient difference in their boiling points.

Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points.

Distillation is used to separate liquids from nonvolatile solids, as in the separation of alcoholic liquors from fermented materials, or in the separation of two or more liquids having different boiling points, as in the separation of gasoline, kerosene, and lubricating oil from crude oil.

Distillation is a process of separating mixtures based upon the principle that if two liquids have different boiling points they can be separated by controlled heating to evaporated one of the liquid and collecting it into another flask after condensation. The other component is left behind in the distillation flask.

DISTILLATION is the purification of a liquid by heating it to its boiling point, causing vaporization, and then condensing the vapors into the liquid state and collecting the liquid. Separation of two or more liquids requires that they have different boiling temperatures.

Separation funnels (see diagram below) facilitates the separation of two immiscible liquids – liquids that don’t dissolve in each other e.g., water and mineral oil.

Melting Point

My Method for separating flour and rice is:

1. Take a beaker.
2. Put a sieve on it.
3. Pour the mixture and shake the sieve gently.
4. Wait for the flour to fall. After the flour falls pour the rice from the sieve into other beaker then do experiment again for fair testing(optional)

Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds.

A common or traditional definition of matter is “anything that has mass and volume (occupies space)”. For example, a car would be said to be made of matter, as it has mass and volume (occupies space). The observation that matter occupies space goes back to antiquity.

Examples of Matter

• An apple.
• A person.
• A table.
• Air.
• Water.
• A computer.
• Paper.
• Iron.

Examples of Liquids

• Water.
• Milk.
• Blood.
• Urine.
• Gasoline.
• Mercury (an element)
• Bromine (an element)
• Wine.

Chair, air, love, smell, hate, almonds, thought, cold, cold drink, smell of perfume. Anything that occupies space and has mass is called matter. Matter can exist in three physical states that are Solid, Liquid, and Gaseous.
