|
Solution
|
A mixture of two or more substances that is uniform at the molecular level.
|
|
|
Alloy
|
A solution of two or more solids.
|
|
|
Solvent
|
The component of a solution that is presented in the greatest amount.
|
|
|
Solute
|
Any component of a solution other than the solvent.
|
|
|
Dissolve
|
To separate and disperse a solid into individual particles in the presence of a solvent.
|
|
|
Solubility
|
The amount of solute that can be dissolved in a specific volume of solvent under certain conditions.
|
|
|
Insoluble
|
A substance is insoluble in a particular solvent if it does not dissolve in that solvent.
|
|
|
Saturated
|
A solution is saturated if it contains as much solvent as the solute can dissolve.
|
|
|
Concentration
|
The ratio of solute to solvent in a solution. For example, a 10% sugar solution contains 10 g of sugar for every 90 g of water.
|
|
|
Equilibrium
|
Occurs when a solution has a maximum concentration of dissolved solute; the dissolving rate equals the rate at which molecules come out of solution (undissolve).
|
|
|
Supersaturated
|
Having a concentration greater than the maximum solubility.
|
|
|
Polar
|
Describes a molecule that has charge separation, like water.
|
|
|
Acid
|
A substance that produces hydronium ions (H3O+) when dissolved in water.
|
|
|
Base
|
A substance that produces hydroxide ions (OH-) when dissolved in water.
|
|
|
pH
|
pH measures the acidity of the solution.
|
|
|
pH Scale
|
The pH scale goes from 1-14 with 1 being very acidic and 14 being very basic. Pure water is neutral with a pH of 7.
