MIXTURES

5th Science

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

EXAMPLES OF SOLUBLE AND INSOLUBLE MIXTURES

SOLUBLEMILK + COCOA POWDER= COCOA DRINK

INSOLUBLEWATER + OIL

Solutions

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

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.

EXAMPLE OF HOMOGENEOUS AND HETEROGENEOUS MIXTURES

• HOMOGENEOUS

• HETEROGENEOUS
