Solutions and Mixtures
A homogeneous mixture with particles too small to settle out.
What is a solution?
Molarity is measured in moles per this unit.
What is liters of solution?
The force responsible for attraction between polar molecules.
What is dipole–dipole attraction?
Solutions with pH values below 7 fall into this category.
What is acidic?
The movement of water across a semipermeable membrane.
What is osmosis?
Compared to colloids, solution particles are this relative size.
What is smaller?
Percent m/v is defined as grams of solute per this amount of solution.
What is 100 mL?
This special intermolecular force occurs when H is bonded to O, N, or F.
What is hydrogen bonding?
Acetic acid is classified as this type of electrolyte.
What is a weak electrolyte?
A solution with the same solute concentration as a cell.
What is isotonic?
A cloudy mixture that eventually separates into layers.
What is a suspension?
How many moles are in 0.20 L of a 2.0 M solution?
What is 0.40 moles?
Which molecule can hydrogen bond: CH₄ or NH₃?
What is NH₃?
At pH 10, which ion has the higher concentration (H3O+ or OH-)?
What is OH⁻?
A cell placed in a hypertonic solution will do this.
What is shrink?
A mixture that scatters light but does not settle out.
What is a colloid?
This percent concentration unit is used when mixing liquids like ethanol and water (think alcoholic beverages).
What is percent volume/volume (% v/v)?
Alcohols dissolve in water due to this type of intermolecular force.
What is hydrogen bonding?
This equation represents the ion product of water at 25 °C.
What is [H₃O⁺][OH⁻] = 1.0 × 10⁻¹⁴?
Removing a product from an equilibrium system causes the reaction to shift this way.
What is toward the products (to the right)?
During dilution, this quantity stays constant.
What is the amount of solute (moles)?
The molarity of a solution made with 10.0 g Na₂CO₃ in 0.250 L.
What is 0.377 M?
The dominant intermolecular force in nonpolar molecules.
What are London dispersion forces?
Strong bases are this type of electrolyte.
What are strong electrolytes?
The principle that predicts equilibrium shifts due to stress.
What is Le Châtelier’s Principle?
