Study Notes
Separating Mixtures
- Passing a mixture of sand and water through a sieve is done to separate the two components based on their sizes and solubility.
- Sand is considered insoluble in water because it doesn't dissolve in water, maintaining its solid state.
Chromatography
- The mobile phase in chromatography is the solvent that moves through the stationary phase, carrying the mixture's components.
Separation of Mixture Components
- The different molecular components of a mixture are separated based on their interactions with the stationary phase and the mobile phase, which differ in their affinities for the components.
PowerPoint Presentation
