FLASHCARD QUESTION
Front
What happens to the volume of a gas when the temperature decreases?
Back
The volume of a gas decreases when the temperature decreases, according to Charles's Law.
2.
FLASHCARD QUESTION
Front
What is the solubility product constant (Ksp)?
Back
Ksp is the equilibrium constant for a saturated solution of a sparingly soluble ionic compound.
3.
FLASHCARD QUESTION
Front
How do you calculate Ksp from molar concentrations?
Back
For the dissociation of BaF2: Ksp = [Ba2+][F-]^2. If [Ba2+] = 3.6 x 10^-3 M, then Ksp = (3.6 x 10^-3)(2 * 3.6 x 10^-3)^2.

FLASHCARD QUESTION
Front
What is the formula for calculating molar mass using osmotic pressure?
Back
Molar mass (M) = (mass of solute (g) * R * T) / Π, where R is the gas constant and T is the temperature in Kelvin.

What is the balanced half-reaction for the oxidation of aluminum?
Back
Al(s) -> Al3+(aq) + 3e-.

FLASHCARD QUESTION
Front
What is the dissociation constant (Ka) for acetic acid?
Back
Ka = 1.8 x 10^-5.
7.
FLASHCARD QUESTION
Front
How do you find the pH of a weak acid solution?
Back
Use the formula: pH = -log[H3O+]. For acetic acid, set up the equilibrium expression and solve for [H3O+].
