Why the product in solvent extraction should be volatile?
The product in solvent extraction should be volatile because this property allows for easier separation from the solvent. When the product is volatile, it can be easily evaporated off from the solvent, leaving behind a purified product. This simplifies the process of isolating and collecting the desired compound.
Why should solvent never touch end of TLC plate?
Solvent should never touch the end of a TLC plate because it can cause the sample spots to dissolve or run off the plate, leading to poor separation and inaccurate results. If the solvent reaches the edge, it can also disrupt the capillary action necessary for the effective movement of the solvent front. Maintaining a proper solvent level ensures optimal chromatography and clearer visualization of the separated compounds.
Why should not the solvent completely evaporate in the recrystallization method of purification?
In the recrystallization method, the solvent should not completely evaporate because residual solvent is necessary to maintain the solubility of the solute in the solution. If the solvent evaporates entirely, the solute may precipitate out prematurely, leading to impurities being trapped in the solid or causing incomplete crystallization. Maintaining some solvent allows for a better-controlled crystallization process, ultimately resulting in purer and more uniform crystals.
What hazards should you be aware of when evaporating a solvent from a solution?
one may inhale the harmful particles of that solution
What do we call a liquid in which substance dissolve?
It is called a solvent, the substance being dissolved is a solute.
Should you take your vitamins with orange juice?
most vitamins should be taken with a meal and a solvent...it does not mater if the solvent is water, juice or milk

How do you make a sentence out of solvent?
Always test the solvent on a small hidden place on the garment before applying it to the stain. A man who is not financially solvent should not ask a woman to marry him.
What should be the solvent other than water and alcohol?
koolaid
Which extinguisher should be used on solvent?
A type B extinguisher.
What are the criteria in choosing a good recrystallization solvent?
Dissolve the entire compound at the boiling point of the solvent.Dissolve very little or none of the compound when the solvent is at room temperature.Have different solubilities for the compound and the impuritiesHave a boiling point below the melting point of the compound so that the compound actually dissolves, not melts, in the hot solvent.Have a relatively low boiling point.

The more-abundant substance in a solution?
in any solution the substanse with the greatest quanity is the
The substance present in the largest amount in a solution?
Solute. No, I believe the answer should be 'solvent'.
What hazards should you be aware of when evaporating a solvent from a solution?

Explain why crystallisation would not be suitable for purifying water?
An ideal crystallization solvent should be unreactive, inexpensive, and have low toxicity.It is also important that the solvent have relatively low boiling point as its best if the solvent readily evaporate from the solid once recovered.For most organic compounds, water is not a good recrystallization solvent.
What is the max height at which the solvent should condense?
half way up...not sure why though
