Unit 8.1: Identifying Characteristics of Solutions Flashcards
Mixtures having a uniform composition and properties throughout
Solutions/ homogenous mixtures
If liquids mix, they are said to be…
miscible
If liquids do not mix, they are said to be…
Immiscible
A chemical will dissolve in a solvent if…
it has a similar structure to the solvent
able to be dissolved
soluble
Unable to dissolve
Insoluble
To separate into ions, applies to ionic compounds dissolved in water
Dissociate
An ion surrounded by water molecules; formed when electrolytes dissolve in water
Hydrates ions
A substance that produced ions when dissolving in water, resulting in a solution capable of conducting electricity, typically, an ionic compound, acid, or base.
Electrolyte
A substance that fully dissociates into ions, or fully ionizes when dissolved in water
Strong electrolyte
A solute is present in (lesser/greater) amounts than the solvent.
Lesser
A substance that dissolves in water as molecules, not as hydrated ions
Nonelectrolyte
To become an ion or ions; applies to acids and weak bases dissolved in water
Ionizes
A molecular compound that dissolves in water primarily as a molecule but ionizes to a small degree, this producing aqueous H+ and an aqueous anion.
Weak acid
A substance that dissolves in water primarily as a molecule, but ionizes to a small degree, thus producing small percentages of hydrated ions.
Weak electrolytes
