and after stirring, it appeared as one substance. You can no longer distinguish one component
from the other. What is the other term for homogenous mixture?
A. Solution B. Dissolution C. solute D. Solvent

8. When sugar dissolves in water, the two substances appear as one. The sugar particles can no
longer be identified. However, the taste of the water proves that the sugar was not lost after
mixing. Its chemical property is retained and so the water taste sweet. What kind of solution is
this?

dissolves in a solvent.
C. The size of the particles affects the dissolving process. The finer the particles are, the
