Why is water often referred to as the "Universal Solvent"?
It can dissolve any known substance.
It dissolves many different substances.
It is the most abundant solvent on Earth.
Polar solvents are generally good at dissolving which types of solutes?
Nonpolar solutes
Polar solutes
Covalent solutes
To calculate concentration, you would use the formula:
Volume of solution / Mass of solute
Mass of solute / Volume of solution
Mass of solute * Volume of solution

In general, increasing the temperature of a liquid solvent increases the solubility of a:
Gaseous solute
Solid solute
Both gaseous and solid solutes
Increasing the pressure of a gas above a liquid generally affects the solubility of the gas in the liquid in what way?
Decreases solubility
Increases solubility
Does not affect solubility
How does pressure affect the solubility of a solid solute in a liquid?
Increased pressure increases solubility.
Increased pressure decreases solubility.
Pressure does not significantly affect solid solubility.
