     • The properties of a mixture are generally intermediate between those of its constituents. Mixtures do not have a fixed composition; the proportion of components can vary.

   Does a mixture of fixed composition have a fixed value?

   • A mixture of fixed composition has fixed values of mole fractions, mass fractions, and molalities, but not necessarily of concentrations and partial pressures. Concentrations will change if the volume changes, and partial pressures in a gas mixture will change if the pressure changes.

   What is the difference between a fixed composition and a variable composition?

   • Have a fixed composition. Can be broken down into simpler substances by chemical means. Examples: Water (H₂O), Carbon dioxide (CO₂). Definition: Combination of two or more substances physically mixed, not chemically bonded. Variable composition. Components retain their original properties.

   How is a mixture formed?

   • A mixture is formed when two or more elements or compounds are present without being chemically bonded together. The substances which have been mixed are not present in specific amounts or ratios like they are in a compound, e.g. two hydrogen atoms for each oxygen atom in water.

   Does salt have a fixed composition?

   • Let’s just assume salt is made out of NaCl and nothing else. So the response to the first question, “Does it have fixed composition?” will be YES, since we know the chemical formula of salt. We know what it is made out of. The response to the next question, “Does it contain more than 1 type of atom?” is YES.

   What is a composition variable for a solute?

   • As the solute mole fractions increase, we say the solution becomes more concentrated. Mole fraction, mass fraction, and concentration can be used as composition variables for both solvent and solute, just as they are for mixtures in general. A fourth composition variable, molality, is often used for a solute.

    Compounds have a fixed, definite composition, meaning they always contain elements in the same proportion by mass. Mixtures, on the other hand, can vary in composition. For example, the proportion of elements in water (H2O) is always the same, but the proportion of salt and water in a saltwater solution can vary.
