This question is not very precise, but I assume you mean which colours will not be separated by chromatography. It is not a property of the colour, but of the substance you are trying to split up. Chromatography only works if the substance is soluble in the liquid you are using to run the chromatogram. Thus some black fountain pen inks separate in water, but the ink from a ball point pen usually does not.
What else can I help you with?
Why is it important to place the developing solvent in a clean dry beaker?
Placing the developing solvent in a clean, dry beaker helps prevent contamination or interference with the chromatography process. Any residues or impurities in the beaker could affect the separation of the compounds being analyzed, leading to inaccurate results. A clean, dry beaker ensures the purity of the solvent and the reliability of the chromatography experiment.
What are other words you could use for chromatography?
Separation technique, analytical separation, molecular separation, chemical separation.
Why do Forensic scientists sometimes use chromatography to investigate paints left at a crime scene and what could this tell them?
Forensic scientists use chromatography to separate the components of paint samples, which can reveal the chemical composition of the paint. This information can help match paint from a crime scene to a particular source, such as a suspect's car, or to determine if different paint samples originated from the same source.
What could potentially limit the effectiveness of the chromatographic technique?
Factors such as column degradation, sample contamination, or improper calibration of the equipment could limit the effectiveness of the chromatographic technique. Additionally, variations in temperature, pressure, or flow rate can also impact the results obtained from chromatography.
What is the point of a control?
The point of a controlled experiment is to assess the effect of one variable in a life process. This could also be for a chemical process.
What is the uncontrolled variable in paper chromatography of pigments?
The temperature of the room could be an uncontrolled variable in paper chromatography of pigments, as it can affect the rate at which the solvents evaporate and the separation of the pigments on the paper. Temperature fluctuations could lead to inconsistent results in the chromatography process.
A hypothesis for paper chromatography?
A hypothesis for paper chromatography depends on what you are making the hypothesis on. A hypothesis for the speed of chromatography could be that you think the speed of the process can be changed depending on the type of paper, or whatever the stationary phase is, and the type of solvent being used.
Which word(s) could be eliminated for a stronger effect mark is in the process of writing his theme?
in the process of
What would happen if an ink pen is used in chromatography?
If an ink pen is used in chromatography, the ink may dissolve and separate into its component colors as it travels along the chromatography medium. However, this could lead to inaccurate results if the ink contains components that are not soluble in the chosen solvent, or if the ink itself is not suitable for chromatographic analysis. Additionally, the dye in the ink could interfere with the separation process and obscure the identification of the intended substances. Thus, using an appropriate marker or solvent-based dye designed for chromatography is essential for accurate results.
How could you put chromatography in a sentence?
eg:-Chromatography is a widely used technique in chemistry to isolate different substances in pure form.
How could you predict the color a leaves will turn in the fall?
Leaf Chromatography
Why could chromatography be used in investigating the crime?
Chromatography could be used in investigating a crime because it can separate and analyze complex mixtures of substances, such as drugs, poisons, or chemicals found at a crime scene. By identifying and comparing different compounds in samples, chromatography can provide valuable evidence to link suspects, victims, or locations to a crime.
What is the point of a controlled experiment?
The point of a controlled experiment is to assess the effect of one variable in a life process. This could also be for a chemical process.
How do you get a multicoloured slide on Microsoft PowerPoint?
Right click on a slide and go to Format Background. You then pick gradient fill or pattern fill and pick mixes of colours. You could also draw things on the slide with different colours to give the effect of mult-coloured slides.
If you are hit in the penis can this stop puberty and its growth?
No, but a severe blow to the testes could effect the process of puberty.
What is correct as would the process that goes into effect ' or as would the process which goes into effect?
In my opinion, "that goes" sounds better than "which goes" in this case. You could get away with either one, however. This is more a question of style than grammar.
What effect does a high pH have on the Danube River and the surrounding ecosystems?
What realistic process could be used to neutralize the river? Explain how the process you suggest would improve conditions.
