Define “solvent”

The liquid in which a substance is dissolved when a solution is formed.

The substance that is being dissolved when a solution is formed.

solute

Define “dissolve”

To disperse particles of one substance (the solute) among the particles of a second substance (the solvent) to create a solution.

A solid that is produced out of a solution when a reaction occurs so both a solid and a liquid are the products.

precipitate

The liquid that passes through filter paper.

filtrate

What would be the best way to treat waste water with undissolved solid pollutants?

filtration

You accidentally dissolved too much sugar in your lemonade You accidentally dissolved too much sugar in your lemonade. Can you filter it out? Why or why not?

No, because the sugar is dissolved.

What process did we use to create the green goo?

precipitation

List all the methods we learned that might be used to treat waste water. (4)

Filtration, precipitation, neutralization, dilution

A factory decides to treat acid wastewater with base until it is neutral. Is it now safe to dump into Puget Sound?

The chemicals are still present but the pH is now neutral.
