The document defines reversible and irreversible changes, with examples of each. It also defines key terms related to solutions, including solute, solvent, dissolve, solution, soluble, insoluble, and solubility. Matching questions are included to match the definitions with the correct key terms.
2. REVERSIBLE CHANGE
A change can be changed back to how it was.
Examples:
A change cannot be changed back to how it was.
Examples:
IRREVERSIBLE CHANGES
3. SOLUTE
A) The action of a solute mixing
with a solvent to produce a
solution.
SOLVENT
Match the definitions with the key words
DISSOLVE
SOLUTION
B) A mixture of a liquid solvent and
a solid solute. The solute dissolves
into the solvent.
C) The liquid into which the solute
dissolves to form a solution.
D) A material that dissolves in the
solvent to form a solution, e.g. salt.
4. SOLUBLE
Material that can be dissolved
in a solvent.
INSOLUBLE
Material that cannot be
dissolved in a solvent and
cannot be turned into a
solution.
LAST ONES
SOLUBILITY
A measure of how easy it is for
a material to dissolve in a
solvent to form a solution.
