Chapter 17: Solutions

Flashcards for Chemistry Chapter 17 covering solutions and their properties.

Solution

Homogeneous mixture of two or more substances.

Solvent

Substance in excess in a solution.

Solute

Substance not in excess in a solution.

Electrolyte

A substance that ionizes in H2O (dissociates into ions).

Strong Electrolyte

Completely ionizes in solution.

Weak Electrolyte

Partially ionizes in solution.

Non-Electrolyte

Does not ionize in solution.

Immiscible

Two substances that do not form a solution.

Colloid

A homogeneous mixture formed by ultramicroscopic particles in dispersal of a medium.

Molarity (M)

moles A / L solution

Molality (m)

moles A / kg solvent

Mole fraction (XA)

nA / n total

Henry's Law

C = k * PA, where C is the concentration of a gas, k is Henry's law constant, and PA is the partial pressure of the gas.
