Science Chapter 2 Review Flashcards
Study
Dissolve
to mix one type of matter into another type of matter to form a solution
Solvent
the larger part of a solution; the part of a solution into which the solutes dissolve
Solute
the smaller part of a solution; the part of the solution that dissolves in the solvent
Dissolving
mixing completely with a solvent to form a solution
Pollution
contaminants in the environment that could harm living things
Soluble
able to dissolve in a specified solvent
Insoluble
unable to dissolve in a specified solvent
Concentrated solution
a solution with a large number of solute particles in a given volume of solution
Dilute Solution
a solution with a small number of solute particles in a given volume of solution
Concentration
the amount of solute present in an amount of solution
Saturated Solution
a solution in which no more solute can dissolve
Unsaturated Solution
a solution in which more solute can be dissolved
Solubility
a measure of how much solute can dissolve in a certain solvent to form a saturated solution at a particular temperature and volume
In a liquid solution
the solute can be either liquid, solid, or gas, however the solvent must be liquid.
In a solid solution
the solvent and solute must both be solid
In a gas solution
both the solute and solvent are gas.
Ways to Increase Solubility of a solute
increase the temperature of the solution, increase the amount of solvent, or use a solvent with similar polarity to the solute.
Ways to decrease solubility of a solute
increase the temperature, change the solvent, or add a common ion.
Calculate Concentration
mass of solute in grams
100mL solution
Calculate solubility
Maximum mass of solute that
will dissolve, in grams
100 mL solvent
