Dilution means adding water to something so that the ratio of solute to solvent is less than in the original solution. Some people say, “Dilution is the solution to pollution.”
Do you think this statement true? Could you ever add enough water so that there would be no drink mix—that the water would be the same as in cup #6, pure water?
Do you think you could you ever add enough water to a pollutant to make it disappear completely? Why or why not?
What is the purpose of environmental remediation?
to restore water to its original purity levels
to make the most of currently used technologies and resources
to remove pollution or contamination from the environment
to reuse materials that would otherwise go to waste

A A greater amount of sugar dissolved in hot water because temperature is directly proportional to the solubility rate of sugar in water.
