Extraction is based on the principle of transferring a substance from one phase to another, typically from a solid or liquid phase to a liquid phase. This is achieved by using a solvent that selectively dissolves the desired substance while leaving impurities behind. The goal of extraction is to separate the desired compound from a mixture.

What are the three major steps involved in metallurgy?
The three major steps involved in metallurgy are mining, beneficiation or ore dressing, and extraction of metal. Mining involves the removal of ore from the Earth's crust, beneficiation involves processing the raw material to improve its quality, and extraction of metal involves obtaining the pure metal from its ore through various methods like smelting or leaching.
How does DNA extraction work and what are the steps involved in the process?
DNA extraction is a process used to isolate DNA from cells. The steps involved typically include breaking open the cells to release the DNA, separating the DNA from other cellular components, and purifying the DNA for further analysis. This is often done using chemicals and physical methods such as grinding, heating, and centrifugation. The extracted DNA can then be used for various applications in research and diagnostics.
Why is distill water used in sodium extract?
Distilled water is used in sodium extraction to prevent any impurities or contaminants from interfering with the extraction process. Using distilled water ensures that only the desired compounds are involved in the reaction and helps to obtain a purer end product.
Why repeated extraction is better than solvent extraction?
Repeated extraction allows for greater efficiency in extracting desired components from a given sample due to the cumulative effect of multiple extraction cycles. This method ensures that more of the target compounds are effectively removed, leading to higher overall extraction yields compared to a single solvent extraction. Additionally, repeated extraction can help to overcome limitations such as incomplete extraction or low solubility that may be encountered with a single extraction.
How does the principle "like dissolves like" apply in the laboratory setting and what are some examples of its practical applications?
The principle "like dissolves like" means that substances with similar chemical properties will dissolve in each other. In the laboratory, this principle is used to predict which solvents will dissolve certain solutes based on their chemical structures. For example, polar solvents like water dissolve polar solutes like salt, while nonpolar solvents like hexane dissolve nonpolar solutes like oil. This principle is applied in various experiments, such as chromatography and extraction techniques, to separate and purify compounds based on their solubility properties.
Which type of principals are involved in extraction of the element?
Extraction of pure metal from ores. That's all on my side.
How does a liquid liquid chromatography work?
The principle is found in "Counter Current Extraction"
What principle is the process of extraction based?
The process of extraction is based on the principle of separating a desired compound from a mixture by using a solvent that selectively dissolves the compound of interest. This is achieved by taking advantage of differences in solubility between the desired compound and the rest of the mixture.
What is the principle involved in the isolation procedure?
DNA isolation is a based on the principle of purification. DNA samples are isolated through the use of physical and chemical methods. Friedrich Miescher conducted the first isolation of DNA in 1869.
What principle is involved in the determination of the volume of an irregularly shaped water insoluble solid?
This is the Archimedes principle.
What is the principle involved in auto pilot?
by satlite waves
What is the principle involved in the isolation of gluten from flour?
solubility.
How is the principle of electrostatics involved in photocopiers?

What is the principle and chemical reaction for the lactose extraction from milk?
The principle behind lactose extraction from milk is enzymatic hydrolysis. The enzyme lactase is added to milk, which breaks down lactose into its constituent sugars, glucose and galactose. The chemical reaction can be represented as: Lactose + Water → Glucose + Galactose
What principle is involved for fluid that go through smaller opening?
The principle involved is known as Bernoulli's principle. This states that as the velocity of a fluid increases, its pressure decreases. Therefore, when fluid flows through a smaller opening, its velocity increases, resulting in a decrease in pressure.
What is the principle involved in wedge film?
The principle involved in wedge film is interference.
What is the principle involved in the brine floatation method?
the principle of this test are used the method of a qualitative test for the detection of nematode and cestode eggs and coccidia oocysts in the faeces.
