Pigment spots in a chromatograph can vary in size due to differences in the molecular weight and polarity of the pigments. Higher molecular weight and less polar pigments tend to travel slower and show up as larger spots, while lower molecular weight and more polar pigments travel faster and appear as smaller spots on the chromatograph.
What else can I help you with?
Define the word pigment in science terms?
In science, a pigment is a substance that gives color to other materials by reflecting certain wavelengths of light while absorbing others. Pigments are often used in biological systems, such as in plants for photosynthesis or in animals for camouflage.
What is the compound that asorbs certain wavelenghts of light and reflects other?
The compound you are referring to is called a pigment. Pigments selectively absorb certain wavelengths of light while reflecting others, which is why they appear with specific colors to our eyes.
What is tin carbonate used for?
Tin carbonate is used for a number of things. It is commonly used to make metal alloys, making glass and soldering iron among others.
Is the density of oxygen smaller than or larger than the density of air?
The density of oxygen is larger than the density of air because oxygen is a component of air, which is a mixture of gases including nitrogen, oxygen, and others. The density of pure oxygen is around 1.43 kg/m^3, while the density of air is around 1.2 kg/m^3 at sea level.
Why are some pigments more soluble than others?
The solubility of pigments depends on their chemical structure, with more polar pigments being more soluble in polar solvents like water. Pigments with functional groups that can form hydrogen bonds or interact with solvent molecules tend to be more soluble. Size and shape of the pigment molecule also play a role in determining solubility.
What items and instruments are used in a lab?
Examples: balance, oven, furnce, burette, pH-meter, glassware, chromatograph, viscometer, refractometer, spectrometer and many others.
What is the main pigment called in plants?
The main pigment of the skin is melanin, it is what makes your skin light or dark whether it be your ethnicity or even the amount of exposure you get from the sun.
What does analyzing the motivations of others mean?
Analyzing the motivations of others involves trying to understand why people behave in a certain way by examining their underlying desires, beliefs, fears, or needs. By understanding these motivations, we can gain insight into people's actions and make better predictions about how they might behave in the future.
What makes a black person black?
The pigment melanin. It's also the pigment that makes suntans. The difference is that some people have that pigment all of the time, and others have it only when needed to protect the skin from repeated sun exposure.
Which is example of a study that is based on a secondary analysis?
Analyzing data collected by others..:)
How does a pigment give a substance color?
by asorbing some colors of light and reflecting others
What happens when the pigment reflects red light?
Answer #1:red light is reflected, all others are absorbed===========================Answer #2:The pigment, and anything it is shmeared on, appears red to the eye.
Is pigment distributed uniformly in each mycelium?
Pigment distribution in each mycelium can vary. In some fungi, pigment may be uniformly distributed, while in others it may be concentrated in certain areas. Factors such as genetics, environmental conditions, and growth stage can influence how pigment is distributed within the mycelium.
Colored substance that absorbs or reflects light?
Pigments absorb certain colors of light, and reflect others. For example, chlorophyll is the pigment in plants which absorbs red and violet light, and relects green. This is why many plants appear green.
Which is an example of a study that is based on a secondary analysis?

What is the plant pigment that captures light?
there are two types. Those are chlorophyls and caratinoyds.
What are two accessory pigments for photosynthesis?
Chloraphyll A and B
