A substance that does not dissolve may fall to the bottom of the container or
may make the water opaque.
It may also form a layer at the top of the liquid.
If a solid makes the liquid opaque, it means you have made a suspension.
This is where the solid particles are more spread out, but they have not broken
down into small enough pieces to dissolve.
You can dissolve a solid in a liquid more quickly by:
• stirring (mixing) the liquid
• increasing the temperature of the liquid
• reducing the size of the particles that you start with.
Think!
Why do these actions dissolve a solid more quickly?
