Solutions – Chemistry Flashcard

alloy
a solid mixture of two metals
aqueous
dissolved in water
concentrated
a solution with a lot of solute; think dark koolaid
concentration
measure of the amount of solute dissolved in a solution
dilute
a solution with only a little bit of solute; think light koolaid
dissociation
when water dissolves a compound; the compound breaks into ions
dissolve
when a compound breaks into ions in a solution
heterogeneous
an unevenly mixed mixture; does not look the same all through
homogeneous
an evenly mixed mixture; looks the same all through
immiscible
two substances that can’t mix, like oil and water
insoluble
not able to be dissolved
mixture
two or more substances mixed together
molality
unit of concentration; the number of moles of solute per kilogram of solvent in a solution
molarity
unit of concentration equal to moles of solute divided by liters of solution
polar
having a positive charge at one end, and a negative charge at the other
saturated
when the maximum amount of solute is dissolved in a liquid
solubility
measurement of how much of a solute can dissolve in a liquid
soluble
able to be dissolved
solute
the substance that dissolves in the solvent, creating a solution (koolaid powder)
solution
A homogeneous mixture of two or more substances, solids, liquids, or gases (koolaid drink)
solvent
The substance the solute dissolves in, with the greatest amount (water in koolaid)
supersaturated
When more solute is dissolved in a liquid than is normally possible
unstaturated
not all of the solute has dissolved in a solution
