Mixtures & Solutions
This type of mixture has the same composition throughout.
What is a homogeneous mixture?
This lab technique separates substances based on how fast they move through a medium.
What is chromatography?
The electrode where oxidation happens.
What is the anode?
A pure substance made of only one type of atom.
What is an element?
Salt water is this type of mixture because the salt dissolves evenly.
What is a homogeneous mixture/solution?
Oil and water are this type of pair because they do not mix.
What is immiscible?
In marker chromatography, this is the part that moves up the paper carrying the dyes.
What is the solvent?
The electrode where reduction happens.
What is the cathode?
The law stating that every compound has the same ratio of elements every time.
What is the Law of Constant Composition?
These electrically charged particles allow electrolytes to conduct electricity.
What are ions?
The substance that does the dissolving in a solution.
What is the solvent?
This real-world use of chromatography helps identify unknown substances in crime labs.
What is forensic testing? (Accept: chemical analysis)
A solution that can conduct electricity because it contains ions.
What is an electrolyte?
A liquid-to-gas phase change that happens below boiling point.
What is evaporation?
When two liquids mix completely, they are described with this term.
What is miscible?
This term describes how much solute can dissolve in a given amount of solvent.
What is solubility?
The reason different pigments travel different distances in chromatography.
What is different solubility/attraction to the solvent?
This process uses electricity to separate water into hydrogen and oxygen.
What is electrolysis?
A method of separating liquids based on different boiling points.
What is distillation?
Color separation in chromatography happens because each dye has a different level of this property.
What is solubility (or attraction to the solvent)?
A mixture in which particles are evenly dispersed at the molecular level but not chemically combined.
What is a solution?
The starting point where the marker is placed on the chromatography paper.
What is the baseline?
This process purifies metals by using electrical current
What is electrorefining?
A solution with a large amount of solute compared to solvent.
What is a concentrated solution?
The reason a solution is considered a physical mixture rather than a chemical change.
What is that the substances keep their identity?
