Overpressured

Attempts to develop an UM chamber were made as early as the 1960s and information was published in an excellent book series on the progress of thin-layer chromatography (TLC) [] and a bit later in a Hungarian instrument journal [] In this simple chamber the adsorbent layer on the chromatoplate is covered by a glass plate in such a way that the end of the cover plate is not immersed in the

Purifying Compounds by Recrystallization

Overview Source: Laboratory of Dr Jimmy Franco - Merrimack College Recrystallization is a technique used to purify solid compounds 1 Solids tend to be more soluble in hot liquids than in cold liquids During recrystallization an impure solid compound is dissolved in a hot liquid until the solution is saturated and then the liquid is allowed to cool 2 The compound should then form

What Are Examples of Solutes and Solvents?

Polar solutes cannot dissolve in non-polar solvents Water is a polar solvent salt and sugar are both polar solutes To dissolve iodine which is non-polar a solvent such as ethyl acetate would be needed and it would not dissolve into water The polarity of each solvent or solute substance depends on the covalent bonds it has between atoms
