Separation technique that identifies parts if a mixture based on how fast different compounds move across a material?
The separation technique you are referring to is called chromatography. In chromatography, different compounds in a mixture are separated based on their different rates of movement across a material (such as paper or a column filled with beads) due to differences in their affinity for the material and the solvent used. This process allows for the identification and analysis of individual components in a mixture.
What is chemical isolation?
You think probable to the separation of compounds from a mixture.
Which physical properties is or are used in the separation of the components of a mixture via chromatography i the abilities of the compounds to absorb ii solubility iii boiling points?
The abilities of the compounds to absorb and their solubility are the physical properties used in the separation of components via chromatography. Boiling points are not typically used in chromatography, as the separation technique relies more on differences in absorption and solubility to separate compounds.
Does polarity of a solvent mixture affect the completeness of the separation in chromatography?
Yes, the polarity of a solvent mixture can affect the completeness of the separation in chromatography. A more polar solvent mixture will tend to separate compounds with different polarities more effectively, leading to better resolution in the chromatogram. However, if the solvent mixture is too polar, it may cause poor separation or elution of certain compounds, affecting the completeness of the separation.
What is the technique called when you pass a magnet over a mixture of iron filings and sawdust?
This is separation of a mixture. It does not have a specific name as it's a special case which only works with iron and a few other magnetic metals such as nickel.
What technique relies on the components of a mixture settling into layers?
Separation by density
What separation technique relies on the components of a mixture settling into layers?
Centrifugation is a separation technique that relies on the components of a mixture settling into layers based on their densities. By spinning the mixture at high speeds, the heavier components move to the bottom, while the lighter components stay at the top, allowing for easy separation.

What is the difference between a substance and a mixture in terms of separation?
A mixture contain two or more compounds; these compounds can be separated with less or more difficulties.

What is liquid -liquid extraction?
separation of immicible solvent

However, if the solvent mixture is too polar, it may cause poor separation or elution of certain compounds, affecting the completeness of the separation.
Explain the term selective solubility?
selective solubility is a separation technique toremove a compound of a mixture. one of the compounds is highly soluble in the medium, whereas the other compound(s) are insoluble. in such a way the compound requested can be removed and purified
Which separation technique would you use to separate the mixture of sodium chloride and water?
You can use the technique of evaporation to separate the mixture of sodium chloride and water. By gently heating the mixture, the water will evaporate, leaving behind the solid sodium chloride.
What separation technique would most likely be used if a solvent we saved?
If a solvent were to be saved, distillation would be the separation technique of choice. Distillation involves heating the mixture to separate components based on their different boiling points, allowing the solvent to be collected and reused.
