What are some ways chromatography can separate chemicals in a mixture?
Chromatography separates chemicals based on their affinity for a stationary phase and a mobile phase, allowing them to travel at different rates. Different types of chromatography like gas chromatography, liquid chromatography, and thin-layer chromatography utilize different mechanisms such as adsorption, partition, ion exchange, and size exclusion to separate the components in a mixture. By adjusting the conditions like solvent polarity, temperature, and column material, chromatography can effectively separate complex mixtures into individual components.
Which chromatographic process would be least likely to be utilized in the crime lab?
Size-exclusion chromatography would be least likely to be utilized in the crime lab compared to other types such as gas chromatography or liquid chromatography. Size-exclusion chromatography separates molecules based on their size, making it less commonly used for the complex mixture analysis typically required in forensic investigations.
What is the name of the method used to separate dyes?
Chromatography is the method used to separate dyes by allowing the components to move at different rates through a medium, such as paper or a column, based on their affinity for the medium and solvent. This technique separates the different dyes based on their molecular interactions with the moving phase.
What chromatography separates lipids?
Thin-layer chromatography (TLC) and gas chromatography (GC) are commonly used to separate lipids based on their chemical properties such as polarity and volatility. TLC separates lipids based on their partitioning between a stationary phase and a mobile phase, while GC separates lipids based on their boiling points and vapor pressures in a gas phase.
What separates substances based on their movement through a special paper?
Chromatography separates substances based on their differing abilities to dissolve in a mobile phase (usually a liquid or gas) and adhere to a stationary phase (such as special paper). As the mixture is carried along by the mobile phase, components with stronger affinity for the stationary phase will move slower, leading to separation based on their solubility and adsorption properties.
What are the four ways a mixture can be physically separated?
The four ways a mixture can be physically separated are filtration, distillation, evaporation, and chromatography. Filtration separates solids from liquids, distillation separates liquids based on their boiling points, evaporation separates solvents from dissolved solids, and chromatography separates components based on their properties like size or solubility.

What is the difference between anion and cation exchange chromatography?
Anion exchange chromatography separates molecules based on their negative charge, while cation exchange chromatography separates molecules based on their positive charge.
What is the difference between cation and anion exchange chromatography?
Cation exchange chromatography separates molecules based on their positive charge, while anion exchange chromatography separates molecules based on their negative charge.
Give atlist 3 methods of separating homogeneous mixture?
Filtration: Separates solid particles from a liquid by passing through a filter. Distillation: Separates components based on differences in boiling points by heating the mixture and collecting the vapors. Chromatography: Separates components based on their affinity for a stationary phase, allowing them to travel at different rates through a medium.

How is chromatography related to tie dying?
Chromatography separates different components in a mixture based on how they interact with a stationary phase and a mobile phase. In tie-dying, different colored dyes are applied to fabric in various patterns to create designs. The dyes separate and interact with the fabric, similar to how components separate in chromatography based on their properties.
What are the key differences between cation exchange chromatography and anion exchange chromatography?
Cation exchange chromatography separates molecules based on their positive charge, while anion exchange chromatography separates molecules based on their negative charge. The key difference lies in the type of charge that is used to separate the molecules.
What chromatography separates lipids?
Thin-layer chromatography (TLC) and gas chromatography (GC) are commonly used to separate lipids based on their chemical properties such as polarity and volatility. TLC separates lipids based on their partitioning between a stationary phase and a mobile phase, while GC separates lipids based on their boiling points and vapor pressures in a gas phase.

Why can we still use the chromatography to determine the relative population of products formed?
Chromatography separates and quantifies different components in a mixture based on their interactions with the stationary and mobile phases. By analyzing the peaks generated by different products on a chromatogram, we can determine their relative amounts based on peak area or height. This allows us to calculate the population of each product formed in a reaction mixture.
