What else can I help you with?
Which part of speech is the word experiment as shown by the dictionary entry?
The word experimen can be a noun or a verb.
Why is acetone a good solvent for extracting chlorophyll-a?
I exactly dont know as why acetone is a good solvent but I know that oen of our labs had ethanol for chlorophyll extraction from the leaf experiment. It does take out most of the chlorophyll present in th leaf and it is commonly used in labs and either acetone or ethanol is used as a solvent choice.
Is acetone an aqueous solution?
Acetone may be considered the solute and air the solvent.
Is glucose soluble in acetone?
Polysaccharides are nonsoluble in acetone. Cold acetone can be used to precipitate polysaccharides to obtain an amount of dry polysaccharide sample.
Function of acetone in gram staining?
Acetone is used for decolouring method, washing away the iodine-crystal violet complex formed in gram negative bacteria. so that the gram negative bacteria can be then stained with safranin or fuchsin.
What is the rf value of xanthaphyll?
The Rf value of xanthophyll can vary depending on the specific conditions of a given chromatography experiment. However, in general, the Rf value of xanthophyll is typically around 0.6 to 0.7 when using silica gel chromatography with acetone and hexane as the mobile phase.
What are the solvents used in gas chromatography calibration?
Common solvents used for gas chromatography calibration include hexane, methanol, acetone, and chloroform. These solvents are often used to prepare standard solutions at known concentrations for calibrating the gas chromatograph and for determining the retention times of analytes.
What happens if the eluent is above the 1.5cm line in a chromatography experiment?
If the eluent is above the 1.5cm line in a chromatography experiment there will not be a proper distribution in a test tube to discover the sources of ink on a paper. A chromatography experiment tests for the sources of ink whether it be chemical or plant based.
How many pigment bands do you see in chromatography experiment?
The number of pigment bands seen in a chromatography experiment will depend on the number of different pigments present in the sample being analyzed. Each pigment will typically appear as a distinct band on the chromatogram.
How does the presence of alcohol and acetone affect the chemical reaction in the experiment?
The presence of alcohol and acetone can affect the chemical reaction in the experiment by potentially altering the rate of the reaction or the final products formed. These substances can act as solvents or reactants themselves, interacting with the other chemicals involved in the reaction and influencing the overall outcome. It is important to consider the specific properties of alcohol and acetone and how they may interact with the reactants in the experiment.
Why Zoe Performs A Chromatograhy Experiment On Waterproof Markers Using Water As A Solven.Will Her Experiment Work Explain Why?
Zoe's experiment may not work because waterproof markers are designed to be resistant to water. The ink in waterproof markers is designed to be insoluble in water, which may prevent the ink components from separating in the chromatography experiment. She would need to use a solvent that can break down the ink in the markers to successfully perform a chromatography experiment.
Does acetone function as a catalyst?
As most catalysts are quite specific in the (or at least the type of) reaction, in others not working at all, I can't give an answer for 'your acetone-reaction'. But to my best knowledge there are very few reactions I can think of being catalysed by acetone; never heard of, you know.
Is periodic acid compatible with acetone?
Periodic acid is usually compatible with acetone. However, the compatibility may vary depending on the specific experiment or application. It is recommended to check the chemical compatibility of periodic acid with acetone in the specific context you are working in.
How can one determine the retention time in a chromatography experiment?
Retention time in chromatography can be determined by measuring the time it takes for a compound to travel through the chromatography column and reach the detector. This time is unique to each compound and can be used to identify and quantify substances in the sample.
How do you change from reversed phase chromatography to normal phase chromatography?

What must be used to make paint split up into various pigments in Chromatography?
If it's an oil paint then you use oil. Paint that thinner or other petroleum-based solvent. If it's a water-based paint, use water. If it's an acetone-based paint, use acetone.
What would be the result if the spots were made to large in a thin layer chromatography experiment?
it would be difficult to read as they would merge
