Why is a chromatogram like a chemical fingerprint?
A chromatogram is like a chemical fingerprint because a fingerprint is diffrent for every single person in the world and to indicate who is who we use fingerprints, for chromatography its a bit diffrent because you can have more than 2 types of the same thing. For example if someone has been killed & they found a little ink next ti the person, they would collect the ink. Then they would find the few people they think are the suspects. They would take a bit of each suspects' ink and then they would use chromatography to indicate who did it (who has the same ink as the murdurer ). So basically a chromatogram is like a chemical fingerprint because they both indicate who is who or who did what.
What happens to the ink spots as the chromatogram develops?
As the chromatogram develops, the ink spots begin to separate and spread along the chromatography medium, typically due to differences in the solubility of the ink components in the solvent used. Lighter or more soluble components travel further up the medium, while heavier or less soluble components remain closer to the origin. This separation allows for the identification of the various pigments or dyes present in the ink, as each component will form distinct spots at different positions on the chromatogram.
How do you find out if a sample ink is pure?
One common way to determine if a sample ink is pure is to use chromatography techniques to separate the components of the ink and analyze their composition. Another method is to compare the sample ink's properties, such as melting point or boiling point, with the known properties of the pure ink. A chemical analysis using spectroscopy techniques can also be employed to identify any impurities present in the ink sample.
When setting up a chromatogram suggest why the base line where dyes are placed is not drawn with a pen?
The baseline where dyes are placed in a chromatogram is typically not drawn with a pen because the ink from the pen could potentially interfere with the separation of the dyes. Using a pen may introduce additional components into the chromatogram that can affect the accuracy and reliability of the analysis. Instead, a pencil or other non-reactive marking tool is typically used to mark the baseline.
Do the ink cartridges that come with my printer have the same amount of ink as the ones you can buy in the store?
No, your printer usually comes with sample ink cartridges.
What problems did ink solve?
Ink solved writing problems, since led was hard to obtain.
How could you tell if a sample of ink is pure?
One way to determine if a sample of ink is pure is by conducting a chromatography test, which separates the components of the ink. If only one component is present, the ink is considered pure. Other methods, such as spectroscopy or chemical analysis, can also be used to determine the composition of the ink and confirm its purity.
Why is the chromatograph line dawn in pencil and not ink?
The chromatograph line is drawn in pencil because pencil marks are more permanent and less likely to smudge when in contact with the organic solvents used in chromatography. Ink can dissolve or spread when exposed to these solvents, affecting the accuracy of the chromatogram.
Is the ink for hp photosmart printers expensive?
Ink for hp photosmart printers is not expensive. There are many places to obtain ink at lower prices that make it reasonable. This type of ink can dry out, so it is prudent to not stock it.
Is there a faster rate of diffusion in ink in water?
Yes, ink diffuses faster in water due to the difference in concentration gradients. Ink particles move from an area of higher concentration to lower concentration more rapidly in water compared to a more concentrated medium.
How can be obtain coloured component from blue or black ink?
To obtain colored components from blue or black ink, you can use a process called chromatography. This involves dissolving the ink in a small amount of water or alcohol and then applying it to a chromatography paper. As the solvent travels up the paper, the different pigments in the ink will separate based on their solubility and affinity for the paper, revealing various colors. This method effectively isolates the individual colored components present in the ink.
When blue ink is heated what do you think has got evaporated from the watch glass?
When blue ink is heated, the water and volatile components within the ink evaporate. This process typically involves the evaporation of solvents like water or alcohol, which are used to dissolve the colorants in the ink. As these solvents evaporate, the pigments may become concentrated, leading to a change in the appearance and consistency of the remaining ink.
