Study Notes
- Pure substance is made from one type of element or compound.
- An impurity is a substance that contains other elements or compounds.
- Solute is a substance that dissolves in a solvent, while a solvent is the liquid in which the solute dissolves, resulting in a solution.
- A high concentration of salt in a solution indicates a large amount of solute in the solvent.
- Mixing a glass of orange juice with a glass of water will result in the orange juice becoming lighter due to the higher amount of water.
- Chromatography is a method to check the number of solutes in a solvent and involves separating substances dissolved in a liquid by allowing the liquid to flow through a chromatogram.
- Chromatography works based on the principles of compound concentration and separating compounds in mixtures.
- Applications of chromatography include drug testing, forensic analysis, and food testing.
