factors affecting solvation
Terms in this set (15)
how does surface area affect the rate a solute dissolves
increasing the surface area increases the rate at which a solute dissolves
How does agitation affect solubility?
agitation increases the rate at which a solute dissolves
how does heating affect the rate at which a solute dissolves
solubility increases with temperature
how does pressure affect the rate at which a solute dissolves
an increase in pressure increases the solubility
which action affects solids and gases differently
what is a solute
the minor component in a solution
what is a solvent
the liquid in which a solute is dissolved to form a solution.
what is the difference between polar and nonpolar substances
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
what does saturated mean
a solution with solute that dissolves until it is unable to dissolve anymore
What does unsaturated mean?
a solution with solute that completely dissolves
what does supersaturated mean
a solution with more solute that contains unidissolved solute
how do you create a solubility curve? what is on each axis?
the relationship between solubility and temperature can be expressed by a solubility curve. the Y-axis is the solubility, and the X-axis is the temperature
how do gases look different from solids and liquids on the solubility curve
gases typically decrease on the solubility curve, solids and liquids typically increase
how do you determine saturated, unsaturated, or super saturated on a solubility curve?
the curved line is saturation, above it is supersaturated and underneath the curve is unsaturated
what happens if the amount of water changes
if the amount of water increases the amount solute increases. if the amount of water decreases then the amount of solute decreases

Choose the best answer for each question. Which of the following explains why astronauts seem weightless in orbit? A) Earth's gravity is much less in orbit. B) The space shuttle is in free fall. C) The gravity of Earth and the Sun cancel. D) The centripetal force on the shuttle balances Earth's gravity.
The crystal structure of sodium is based on the body-centered cubic unit cell. What is the mass of one unit cell of Na?
Which of the following molecules have net dipole moments? For the molecules that are polar, indicate the polarity of each bond and the direction of the net dipole moment of the molecule.
