    Pure water freezes at 0C in normal conditions.

    Impure? Depends on the impurities. The higher the concentration of salts in seawater the lower the freezing temperature.

    The freezing point of seawater decreases as salt concentration increases. At typical salinity it freezes at about −2 C(28 F).
    from Seawater - Wikipedia, the free encyclopedia

    So if you made a mixture of half and half seawater and pure water the freezing point would be somewhere between 0C and -2C.

    Do you have any specific problem that your question relates to?
