Which solvent can be removed from insoluble solute?
sand and water
Why must the chromatogram be removed before the solvent travels the entire length of the paper?
So that you can measure how far it traveled.
What happen if turpentine stains a tuxedo?
Turpentine is a rather powerful solvent. The stain cannot be removed. Buy a new tuxedo.
What is Thin Layer Chromatography?
Thin-layer chromatography consists of a stationary phase immobilised on a glass or plastic plate and a solvent as mobile phase. The sample, either liquid or dissolved in a volatile solvent, is deposited as a spot on the stationary phase. The constituents of a sample can be identified by simultaneously running standards with the unknown spot. One edge of the plate is then vertically placed in a solvent reservoir and the solvent moves up the plate by capillary action. When the solvent front reaches the other edge of the stationary phase, the plate is removed from the solvent reservoir. The separated spots are then visualized with ultraviolet light or by a suitable reaction procedure....:)
What do we call a liquid in which substance dissolve?
It is called a solvent, the substance being dissolved is a solute.
Which solvent can be removed from insoluble solute?
sand and water
What factors determine the point at which a given solute solvent combination reaches equilibrium?
This solvent is saturated with that solute. Saturation equilibrium.
What happens when a solution reaches the saturation point?
Saturation is the point a solution reaches where no more solute will dissolve in the solvent.
What impurity is removed during the recrystallization process?
Only those impurities can be removed which are soluble in solvent used.

What is protein filtration?
A sample of blood, serum, or plasma from which all proteins have been removed by chemical or physical denaturation, dialysis, ultrafiltration, or solvent extraction.
How do you remove caterpillar poop off concrete pavers?
Caterpillar excrement is an organic substances. Therefore, it can be removed from concrete using an organic solvent such as acetone.

It is called a solvent, the substance being dissolved is a solute.
How do you remove wax from crude oil?
Wax is not removed from crude oil until it reaches the refinery. Several processes allow for the removal of wax from crude oil. In many cases the wax is not removed at all, but sent as residue to be broken down thermally in a coking unit or visbreaking unit. Other options include solvent dewaxing which involves adding a large amount of solvent in a ratio of 3:1 to 12:1 to remove the wax in a heavier product known as pitch. Solvent dewaxing is a dated process, and today wax removal is more commonly accomplished by using a catalyst at high temperature and pressure to isomerize the waxy "paraffin" molecules into more usable products (isoparaffins). Isoparaffins have a better viscosity index than paraffin and are typically used as lubricating oils for engines, turbines, etc.
How do you remove yellowing from vinyl flooring?
yellowing in vinyl usually means the plasticizes in the product have reacted to something ie. water or solvent. this yellowing can not be removed sorry.
