What are some possible alternatives for paper chromatography?
Some possible alternatives for paper chromatography include thin-layer chromatography (TLC), gas chromatography, high-performance liquid chromatography (HPLC), and capillary electrophoresis. These techniques offer different separation mechanisms and have varying applications depending on the analyte and desired outcome.
How does chromatography work to separate particles of ink?
Chromatography works to separate particles of ink by exploiting differences in solubility between the ink components and the mobile phase (solvent). As the mobile phase moves through the stationary phase (usually a paper or column), it carries the ink components at different rates based on their solubility. This differential movement results in separation of the ink particles into distinct bands or spots on the chromatography paper.
Why methanol is a good solvent for uv and not fof ir r?
Methanol is a good solvent for UV spectroscopy because it has a wide transparent region in the UV spectrum, allowing it to effectively dissolve various solutes without interfering with the UV absorption measurements. However, it is not suitable for infrared (IR) spectroscopy since methanol has strong IR absorbance due to its O-H and C-H bonds, which can obscure the spectral features of the analytes being studied. This characteristic makes methanol useful for UV analysis but problematic for IR applications.
Why methanol is used for strychnine analysis?
Methanol is commonly used for strychnine analysis because it is a good solvent for extracting strychnine from samples. Methanol can efficiently dissolve strychnine and is compatible with commonly used analytical techniques, making it a suitable choice for sample preparation and analysis in strychnine detection.
Is methanol good solvent for extraction?
Methanol is a commonly used solvent for extraction due to its polar nature and ability to dissolve a wide range of compounds. However, it is important to consider the toxicity of methanol and ensure proper safety precautions are taken when using it for extractions. It is also important to be aware of the regulations and guidelines surrounding the use of methanol in extraction processes.
What is a good solvent to extract Rhodamine B out of a highliter?
methanol
Why was methanol an appropriate solvent to precipitate polystyrene?
Methanol is used to force polystyrene OUT of solution. So the simple answer is: you can't. But, there is probably an extreme temperature or pressure that allows polystyrene to remain in solution with methanol present.

These techniques offer different separation mechanisms and have varying applications depending on the analyte and desired outcome.
How can paper chromatography be used to separate pigments based on their chemical and physical properties?
It is an appropriate technique to use because it separates the pigments, so one can see which pigments are present, even if some pigments are normally hidden to the naked eye.
Why is water not the best solvent to use in paper chromatography?
acetone or butanol That totally depends on the solute you are trying to separate. Methylene Chloride generally works much better as an all around solvent due to its mild polarity and organic functional groups. Acetone won't work at all if you have 2 polar solutes. They will travel with the solvent front and not separate at all! In other words, it depends on your solute. Cheers, Ty

Is methanol soluble?
Yes, because Methanol contains an OH bond. This is why when 50 millilitres of each only make 95mils or so.
Why is rubbing alcohol a good solvent for chromatography testing?
Rubbing alcohol is a good solvent for chromatography testing because it is able to dissolve a wide range of substances, making it effective at separating different compounds. The polarity of rubbing alcohol allows for good separation of compounds based on their molecular interactions with the solvent and the stationary phase. Additionally, rubbing alcohol evaporates quickly, which aids in the visualization of separated compounds.
Why is filter paper used in chromatography?
Filter paper is used in chromatography because it is porous and allows the solvent to travel through it by capillary action. This helps separate the components of a mixture based on their solubility and affinity for the stationary phase. The filter paper also provides a large surface area for the separation to occur effectively.
What is Good example of solvent?
Water is a commonly used solvent for many things (tea and coffee, in urine and sweat, in lab work involving certain chemicals). Hexane, cyclohexane and methanol are all often used to dissolve organic compounds.
