AIM 2: What is a liquid solution?
You can be a magician! Just add sugar to water
and stir. Abracadabra! The sugar disappears!
But is it really gone? No. The sugar and water just
mix together. They mix completely. The sugar just seems
to disappear.
Sugar and water together form a mixture. There are
several kinds of mixtures. Sugar and water form a special
kind of mixture called a liquid solution.
A liquid solution has two parts: a solute [SOLL yoot]
and a solvent [SOLL vent]. The solvent is always a liquid
in a liquid solution. The solute is what “disappears” in the
solvent. The solute may be a solid, gas, or another liquid.
A liquid solution is formed when the solute
dissolves. The solute spreads out evenly throughout the
solvent, which is also called homogenous. The substance
that gets dissolved is said to be soluble.
In the example of sugar and water, the water is the
solvent and the sugar is the solute. Water dissolves the
sugar. Sugar is soluble in water.
There are many kinds of solvents and there are
many kinds of solutes. There are also many kinds of liquid
solutions.
LIQUID SOLUTIONS & STATES OF MATTER
All the examples in Figure A, B, and C are liquid solutions
Remember, solutions are made with three states of matter—solid,
liquid, and gas, which are the choices for each blank
space.
1. a) Name the states of matter in this
liquid solution (Figure A).
____________ and ____________
b) The solute is the _____________.
c) The solvent is the ____________.
2. a) Name the states of matter in this
liquid solution (Figure B).
____________ and ____________
b) The solute is the _____________.
c) The solvent is the ____________.
3. a) Name the states of matter in this
liquid solution (Figure C).
____________ and ____________
b) The solute is the _____________.
Remember, a mixture is a liquid solution only if the
solute completely dissolves and spreads out evenly.

c) The solvent is the ____________.
