In the separation of pigments, such as during chromatography, the pigments often carry a negative charge. This is due to the presence of functional groups in the pigments that can ionize in solution, allowing them to interact differently with the stationary and mobile phases based on their charge and polarity. The varying charges and polarities of the pigments contribute to their differential movement through the medium, leading to their separation.

What charge is carried by the pigments in electrophoresis separation?
In electrophoresis separation, pigments typically carry a net charge that can be either positive or negative, depending on their chemical structure and the pH of the buffer solution. At a specific pH, the pigments ionize, resulting in a charge that influences their movement in an electric field. Anions will migrate toward the anode (positive electrode), while cations will move toward the cathode (negative electrode). The charge and the size of the pigments ultimately determine their separation efficiency during the process.
What charge is carried by the dye pigment in the separation?
The charge can vary depending on the type of dye pigment used, but typically dye pigments carry a negative charge. This allows them to be separated using an electric field in techniques like electrophoresis.
Why are the pigments carried are carried up the filter paper?
Pigments are carried up the filter paper during chromatography due to a combination of their solubility in the solvent and their interaction with the paper. As the solvent moves up the paper by capillary action, it dissolves the pigments and transports them along with it. Different pigments have varying affinities for the paper and the solvent, causing them to travel different distances, which allows for their separation and identification. This process relies on the principles of differential migration based on polarity and solubility.
Are there 3 or 2 types or charge?
There are three type of charges +ve ,-ve and neutral.
Why do some pigments move farther up the chromotogram tha others?
Pigments move at different rates in chromatography because they have varying molecular weights, sizes, and polarities. Lighter, less polar pigments travel faster because they interact less with the stationary phase and are carried further by the mobile phase. Heavier, more polar pigments move more slowly as they have stronger interactions with the stationary phase.
How are different pigments carried up filter paper?
Pigments are not carried up filter paper, dyes are. But they are carried up in solvents.

Define negative charge without using mass of electron?
Mass and charge are not connected. Negative charge is the charge carried by an electron.
What are the two charges of electricity?
The two charges of electricity are positive and negative. Positive charge is carried by protons, while negative charge is carried by electrons.
What are the two kinds of electric charge?
The two kinds of electric charge are positive and negative. Positive charge is carried by protons, while negative charge is carried by electrons. Opposite charges attract each other, while like charges repel.
