(Paper Chromatography)

1. What carrier solution might work well to separate newspaper inks? Why?

2. What carrier solution might work to separate different salts? Why?

3. What carrier solution might work to separate different fatty acids?
Why?

I really have no idea what the answers could be. I tried searching google but couldn't find much. Please help and link your sources!!

1. When it comes to separating newspaper inks using paper chromatography, a suitable carrier solution is usually a mixture of solvents such as water and ethanol (or isopropyl alcohol). This combination is effective because it helps to dissolve and carry the inks as they move up the chromatography paper. The water component helps to dissolve water-soluble inks, while ethanol (or isopropyl alcohol) is effective at dissolving alcohol-based inks. Since newspaper inks can consist of a combination of both water-soluble and alcohol-based inks, a mixture of these solvents often provides good separation.

2. To separate different salts using paper chromatography, one typically uses a specific carrier solution based on the polarity of the salts. A popular carrier solution for this purpose is a mixture of water and a polar organic solvent such as acetone or methanol. The water component allows for the separation of more polar salts, while the organic solvent component can separate less polar salts. You can experiment with different ratios of water and the organic solvent depending on the specific salts you are trying to separate.

3. When it comes to separating different fatty acids, a common carrier solution is a nonpolar solvent. This is because fatty acids are typically nonpolar compounds. An effective nonpolar solvent for this purpose is usually a mixture of hexane and diethyl ether. These solvents have low polarity and are good at dissolving nonpolar compounds. The specific ratio of hexane to diethyl ether can vary depending on the fatty acids being separated.

While I couldn't find specific sources to link, the information provided is based on general knowledge of paper chromatography techniques. It's important to note that the specific carrier solutions mentioned may vary depending on the desired separation and the composition of the substances being studied. It is always recommended to consult scientific literature or consult with a chemistry expert for more precise information.
