What is the purpose of the filter paper inside the developing chamber in chromatography?
The filter paper helps to evenly distribute the solvent vapor within the developing chamber, allowing for uniform separation of the components in the sample. It also acts as a medium for the sample to travel along with the solvent, facilitating the separation process in chromatography.
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 the solute solvent and the purpose for purose cream?
In a cream formulation, the solute typically consists of active ingredients or emulsifiers, while the solvent is usually water or oil that serves as the base. Purpose cream, often used for skin care, aims to hydrate, nourish, and protect the skin, providing a barrier against environmental factors. The combination of solute and solvent creates a stable mixture that enhances the cream's effectiveness and texture.
What would happen if the Spot of origin is lowered into the solvent in chromatography?
If the original spots were below the level of developing solvent then the components of the spotted sample would dissolve into the solvent and no spots would be seen upon analysis because all of the sample is dissolved in the developing solvent. hope this helps. good luck in o. chem!
What is S280 solvent?
This solvent is used to clean surfaces from polyester resins.
Is phenol a solvent?
Phenol is a compound that can act as a solvent for certain substances, but it is not commonly used as a general-purpose solvent due to its strong acidity and potential health hazards. It is most often used in the production of other chemicals and industrial processes.

What is the Rf value of caffeine in the solvent acetyl acetate?
The Rf value of caffeine in acetyl acetate solvent depends on the specific experimental conditions, such as the type of chromatography paper used and the developing solvent system. Typically, caffeine has been reported to have an Rf value around 0.5 in acetyl acetate solvent systems.
What is the industrial purpose of water?
Water is used as solvent, cooling agent, cleaning agent, reactant, for electrolysis in many industries.

Will acetaminophen or ibuprofen have a higher Rf if you carry out a TLC separation of on a silica gel using a non-polar developing solvent?
Acetaminophen will have Rf value of about 0.4 and ibuprofen will have Rf value of about 0.6 if the non polar solvent used is ethanol.
What is a sentence stating an opinion or belief as the purpose for developing a paper?
A sentence stating an opinion or belief as the purpose for developing a paper is called a thesis statement.
What is a super solvent?
A super solvent is a solvent that has exceptional dissolving power and can effectively dissolve a wide range of substances. These solvents are often used in industrial applications where regular solvents are not effective.

What is a type of solvent that uses alcohol?
Ethanol is an alcohol that can be used as a solvent.
What is S280 solvent?
This solvent is used to clean surfaces from polyester resins.
