What is a necessary condition for extraction of a substance from an aqueous solution?
There must exist a solvent for the substance to be extracted in which this substance's solubility is greater than the substance's solubility in water, and the solvent also must not be miscible in water, so that an interface between the solvent and water will be formed in a mixture of the two.

Steps for the preparation of a standard solution?
1. Weigh the necessary substance 2. Put this substance in a bottle or Berzelius, Erlenmeyer flask. 3. Add slowly the adequate volume of solvent and stir. 4. Apply a label (date, name of the operator, name of the solution, concentration, etc.).
What is a substance that can dissolve another substance called?
The substance (usually a liquid) that can dissolve another substance is called a solvent.The substance that is being dissolved in a solution is called the solute.
Is The substance being dissolved in a solution is called a solvent.?
Nope - the substance being dissolved is the solute. The solution in which the substance is being dissolved - is the solvent.
Why do we use NaOH solution in the extraction procedure?
NaOH solution is used in the extraction procedure to adjust the pH of the solution, making it more basic. This helps to separate the desired compound from impurities by promoting the formation of a water-insoluble compound that can be easily separated.
What is a substance called that does not dissolve?
A substance is insoluble when it cannot be dissolved into a solution.
Why volume of toluene decrease after extraction?
It may trapped in your sample, if it's a polymer for example. Or it may reacted with a substance in the solution.
What two requirements are necessary for a substance to be an eletrolyte?
For a substance to be an electrolyte, it must be able to ionize or dissociate into ions in solution. Also, it must conduct electricity in solution due to the presence of these free ions.
Is the extraction of a liquid from a liquid solution is called liquid liquid extraction?
Yes, it is correct.
Steps for the preparation of a standard solution?
1. Weigh the necessary substance 2. Put this substance in a bottle or Berzelius, Erlenmeyer flask. 3. Add slowly the adequate volume of solvent and stir. 4. Apply a label (date, name of the operator, name of the solution, concentration, etc.).
Is the substance that is dissolved in a solution?
The substance that is dissolved in a solution is a solute. A solvent is the dissolving medium in a solution.
Why did we use salt in the extraction solution?
Salt was used in the extraction solution to help separate the DNA from other cellular components by creating a high-salt environment that causes the DNA to clump together and precipitate out of the solution.
Substance that is dissolved in a solution?
The substance that is dissolved in a solution is called a solute. It is typically present in smaller quantities compared to the solvent, which is the substance that dissolves the solute in the solution.
What is a substance that can dissolve another substance called?
The substance (usually a liquid) that can dissolve another substance is called a solvent.The substance that is being dissolved in a solution is called the solute.
Why is sodium carbonate added during solvent extraction?
Sodium carbonate is added during solvent extraction to adjust the pH of the solution. This helps in increasing the solubility of the desired compound in the organic solvent phase, leading to better extraction efficiency. Additionally, sodium carbonate helps in neutralizing any acid impurities present in the solution, preventing them from interfering with the extraction process.
Is The substance being dissolved in a solution is called a solvent.?
Nope - the substance being dissolved is the solute. The solution in which the substance is being dissolved - is the solvent.
When you dissolve a substance in a liquid do you get an alloy compound or a solution?
When you dissolve a substance in a liquid you get a solution.
Role of tris in extraction of DNA?
To give the solution buffering capacity.
