You could try experimenting with chromatography.
- Cut strips of filter paper or paper napkin
- Put a dot of each ink a small ways in from the end of a strip
- Put that end (but not the dot of ink) into a liquid that may dilute at least some of the liquid in the ink:
Suggestions : do different strips with water, alcohol, other solvents
- Compare the results after some time,
The liquid solvent will carry different pigments different distances along the paper substrate and will most probably show differences for different inks.
What else can I help you with?
Assume you had a mixture of solid na2co3 and nacl could you use only h2so4 to determine whether or not na2co3 was present explain?
Yes, you could use H2SO4 to determine the presence of Na2CO3 in the mixture. When H2SO4 is added to the mixture, effervescence will be observed due to the reaction between Na2CO3 and H2SO4, producing CO2 gas. This effervescence confirms the presence of Na2CO3 in the mixture.
Is sand a compound or an element or an homogenous mixture or a heterogeneous mixture?
The purest sand is a compound, silicon dioxide. Most ordinary sand, however would contain some other materials and could be either a homogeneous or a heterogeneous mixture.
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 mixture of gaseous elements and compouds?
A mixture of gaseous elements and compounds could contain various gases like oxygen, nitrogen, carbon dioxide, and water vapor. The gases can exist together without chemically combining to form a new substance. This mixture might be found in the Earth's atmosphere or industrial processes.
Could the presence of different pigments be detected before separation by chromatography?
Yes, the presence of different pigments can be detected before separation by chromatography through techniques such as UV-Vis spectroscopy or fluorescence spectroscopy. These techniques can provide information about the absorption or emission properties of the pigments present in a sample.
What pouch may contain various colored pigments?
Plastids :) Took me a while to find the answer.... wasn't in my textbook!
Could only H2SO4 be used to determine the presence of Na2CO3 in a mixture of solid Na2CO3 and NaCl?
yes
What are pigments useful for?
pigments are used for people who have lost there pigment and then they could replace it with the pigment they have

How could you demonstrste that blood is mixture?
Blood contain a high numbers of components as proteins, antibodies, salt, other ions, oxygen, hemoglobin, cells, etc.
Is potpourri like spice?
A potpourri is a mixture of dried fragrant plant material used to scent a room. It is not a single item. However, it could contain a spice if the smell was acceptable.
What to do if car is overheating in the winter?
First you have to determine the cause. Could be a faulty thermostat, frozen coolant (insufficient mixture of antifreeze), low on coolant or possibly a bad head gasket.
What is green pigment found in photosynthesizing organisms?
well green pigments on the photosynthesizing organism is there so it could help it with the process of photosynthesis. the green pigments help trap light so it could be used with carbon dioxide and water to make glucose and oxygen. plants are autotrophs this means they make their own food. the green pigments help them in this process.

Do Skittles contain beetles?
They could contain bugs
