• in a solution, the substance in which the solute dissolves.
•water

Dissolve• When the solute disappears
and is absorbed into the solvent.
• Stirring helps the solute to dissolve.

Solution• A mixture of 2 or more
substances uniformly dispersed throughout a single phase.
• The Kool-aid drink is a solution when mixed.

Concentrated• The amount of a particular
substance in a given quantity of a mixture.
• When Kool-aid powder was dissolved in a glass of water it was more concentrated than when it was mixed.

Homogeneous• a mixture that has the same
uniform appearance & composition throughout.
• When the sugar & Kool-aid are dissolved completely, the solute is evenly spread out throughout the mixture.

Heterogeneous• a mixture that visibly has different
substances or phases.
• When ice was added a solid was visible in the liquid and the mixture was not the same throughout.
