What  is asolution    ?
Water    No matter what    you do to it    physically -- boil,    freeze, stir, shake,    strain -- it is still    water.3
Salt Water    If you boil salt    water, the water    turns to gas and    leaves the salt    behind.4
Pulpy Orange    Juice    If you strain pulpy    orange juice, it loses    its pulp.5
SubstancesWater, salt water and pulpy orange juice are different. These differences can be explained using CHEMISTRY!    ...
