What is the solvent front and how is its migration on the TLC plate measured?

The solvent front is the line at where the solvent moves up the TLC plate. Its migration can be measured by taking the R value of the TLC plate.

What forces the eluting solution to move along the chromatographic support material?
An eluting solvent is then allowed to move up the plate by capillary action, drawing the components of the mixture along by varying degrees.Read more: chromatography
Why do plate tectonics have names?
It is a suitable name because tectonics comes from the Greek word tekton which means builder, and plate tectonics refers to the building of the features on Earth's surface due to deformation caused by plate movements...
How have scientists figured out that the pacific plate is moving at about nine centimeters per year?
All of the tectonic plates move, but they move at different speeds depending on which plates are involved. The Pacific plate moves slightly more than four centimeters annually.
What lithospheric plate is the largest?
The last person to answer was a complete and total idiot. The correct answer is the Pacific Plate.
What is a sentence for plate?
Plate tectonics is a theory that the Earth's crust is divided into many plates that glide over the mantle.He forgot to step on home plate so the umpire said he was out.That necklace is made of gold plate not solid gold.
Is the 60 foot 6 inch distance from mound to plate measured at the front of the plate or the apex?
The distance is measured from the back of home plate to the hill. Hope that helps Answer More accurately, the distance is measured from where the first and third base lines meet (the apex of the plate) to the front edge of the pitcher's plate.
Is the distance between the back of the plate or the front of the plate in softball for little girls?
The distance is always measured from the point or tip of the plate.
How is the rubber to homeplate in girls fastpitch measured?
From the front of the mound to the back of the plate
What happens in paper chromatography in inorganic ions?
Migration of any species in a chromotography plate/paper is regulated by the solvent. Beyond that, your question has no answer because it does not actually mean anything.
Is the distance in fastpitch softball measured from the pitching rubber to the front of home plate or the back of home plate?
According to the official rule book, the bases are located inside the diamond.If you were standing on the pitcher's mound, then no matter which base you look at, the measurements would be behindthe bases, because the back corners of each base is what touches the measured diamond.Home plate is measured from the point (the part that points to the catcher) to the far right corner of first base (which touches the foul line). First base to second base is measured from the foul line to the center field corner of second base, etc.
What is the distance home plate to the oitcher's mound?

What would be the consequence of having so much solvent in the developing chamber that it would cover the application?
If the solvent level in the developing jar is deeper than the origin (spotting line) of the TLC plate, the solvent will dissolve the compounds into the solvent reservoir instead of allowing them to move up the plate by capillary action. Thus, you will not see spots after the plate is developed. These photos show how the yellow compound is running into the solvent when lifted from the developing jar.
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....:)
