  1. If you are talking about a NON-VOLATILE SOLUTE you are right. It may or may not be true with a volatile solute and volatile solvent.
    When a non-volatile solute dissolves in a volatile solvent, three things happen.
    a. The vapor pressure of the solvent is lowered,
    b. The boiling point of the solvent is raised,
    c. The freezing point of the solvent is lowered.

    The extent to which these three things happen depends SOLELY upon the number of dissolved particles.
