based on the separation of the dyes using liquid chromatography，are the red and blue dyes chemically or physically combined in the kool aid? why?

Solutions

Expert Solution

Basically, liquid Chromatography is used to separate components of a mixture that are physically combined,In other words ,the components do not react with each other (no chemical combination).

Explanation: In this method, physically combined components of a liquid mixture is made to get distributed between two different phases-stationary phase and the mobile phase.The stationary phase is adsorbing substances like cellulose paper(used in paper chromatographic methods) or silica gel or alumina (used in column chromatography to separate liquids).The mobile phase is the solvent that selectively brings the components of the mixture along with it as it move through the stationary phase, basis the comparative dissolution of the components in the solvent.

answer: The dyes are physically combined,else they could not be separated using liquid chromatography

Size exclusion chromatography (SEC) is a technique that allows for separation of molecules based on their size. If organic solvents are used to separate polymers, this application is referred to as gel permeation chromatography, and when aqueous solvents are used to separate proteins and soluble macromolecules, this is known as: a.) Titration b.) Paper chromatography c.) P60 chromatography d.) Silica gel column chromatography e.) Gel filtration chromatography

The separation of solid particles into different fractions based upon their terminal velocities in a liquid is called hydraulic classification. For example, consider two particles with different settling velocities placed in a rising current of water. If the water velocity is adjusted to a value between the terminal settling velocities of the two particles, a separation will result: the slower- settling particle will move upward with the water while the faster settling particle will settle out to the bottom. A...
