Activity 1Activity 1Solutions are found at home and
in the environment.Solutions are made up of solutes
and solvents.Solutions can be solid, liquid or
gas.Solutions can be naturally
occurring or manufactured.

Activity 2Activity 2Solutions have only one phase,
thus, a uniform appearance.The components of a solution
cannot be separated through filtration because their particles are very small that they can pass through the holes of the filter paper.

Activity 3Activity 3A saturated solution is a solution that
contains the maximum amount of solute that the solvent can dissolve.
The presence of excess solute that can no longer dissolve is the evidence that a solution is saturated.
An unsaturated solution is a solution that contains less solute than the maximum amount that the solvent can dissolve.

Concentrations of Concentrations of solutionssolutionspercent by volume – amount of
solute in a given volume of solution (g/100 mL)
percent by mass – amount of solute in a given mass of solvent (g/100g)

Stirring causes the particles of solute
and solvent to move faster increasing
the chances of contact.

ProceduresProceduresAdd 50 mL of water
into 2 identical containers.
Add 5 grams of rock salt to one container and 5 grams iodized
salt to the other container.
Record the time it takes the salt to
dissolve in each of the containers.

Smaller particles have more edges and corners
where the solvent can be in contact. Thus, the smaller the particle of salt, the
easier it mixes with water.
