Solutions Flashcards
Define solutions
homogenous mixtures composed of a major component that is a liquid and a minor component that is dissolved in the liquid
What are homogenous mixtures composed of a major component that is a liquid and a minor component that is dissolved in the liquid?
solutions
What is the major component of a solution called?
solvent
What is the minor component of a solution called?
solute
How does mixing affect entropy?
mixing leads to an increased entropy
What is lattice energy?
Lattice energy is the energy required to pull the solute apart
What is the energy required to pull the solute apart?
lattice energy
Should the lattice energy be positive or negative for a solution?
positive
What is the enthalpy of solvation?
the energy released when the solute interacts with the solvent
What is the energy released when the solute interacts with the solvent?
enthalpy of solvation
Should the enthalpy of solvation be positive or negative for a solution?
negative
What does miscibility mean?
o If two liquids mix in any proportions we call them miscible. If they don’t they are immiscible
What does Henry’s Law state?
states that the mole fraction of gas dissolved in the liquid (like the concentration) is directly proportional to the pressure of the gas over the liquid
What law states that the mole fraction of gas dissolved in the liquid (like the concentration) is directly proportional to the pressure of the gas over the liquid?
