Mixtures can be either soluble or insoluble depending on whether a solute dissolves in a solvent to form a solution. Soluble mixtures like milk and cocoa powder form homogeneous solutions when mixed, while insoluble mixtures like oil and water form heterogeneous mixtures and the substances can be easily separated. The factors that influence whether a solute dissolves include mixing, quantity of solvent, heat, and time.

5th Science

2. MIXTURES:
soluble and insoluble
• We can distinguish between soluble and
insoluble mixtures.
• To make a solution there is a solute substance
and a solvent substance.
• If a substance dissolves it’s a soluble, so we
make a new solution. For example: water+salt

3. EXAMPLES OF SOLUBLE AND
INSOLUBLE MIXTURES
SOLUBLE
MILK + COCOA POWDER= COCOA DRINK
INSOLUBLE
WATER + OIL

4. Solutions
• There are things that help solutes to dissolve.
- MIXING
- QUANTITY OF SOLVENT
- HEAT
- TIME

5. MIXTURES: homogeneous and
heterogeneous
• Anytime you combine two or more different
things, you make a mixture.
• We can distinguish between homogeneous and
heterogeneous mixtures.
What’s the difference?
• In homogeneous mixtures you can not distinguish
everything, you can not separate them. So, they
are ususally irreversible.
• In heterogeneous mixtures you can distinguish
everything, you can separate them. So, they
could be reversibles.
