This document discusses properties of solutions including:
- Types of solutions defined by the states of the solute and solvent.
- Terms used to describe solution composition such as dilute, concentrated, molarity, mass percent, mole fraction, and molality.
- Molarity is expressed as moles of solute per liter of solution and is dependent on temperature while molality is independent of temperature.
- Heat of solution is the enthalpy change of dissolving a solute and is the sum of enthalpy changes from solute particles separating and solvent particles making space.
- Solubility is influenced by entropy; the mixed state has many more configurations than the unmixed state.
3. Types of Solutions State of solution State of solute State of solvent example gas gas gas air, natural gas liquid gas liquid carbonated water solid gas solid hydrogen in platinum liquid liquid liquid alcohol and water liquid solid liquid sea water solid solid solid metal alloys
