  • When comparing ice formed on fresh water to ice formed on salt water, the key difference is that saltwater ice will have a lower freezing point than freshwater ice due to the presence of salt, meaning it will need a colder temperature to freeze; additionally, when saltwater freezes, the ice that forms is primarily composed of freshwater as the salt is expelled into the surrounding liquid, making the ice itself relatively "fresh" even though it came from saltwater.
    Key points about freshwater and saltwater ice:
    Freezing point:
    Freshwater freezes at 32°F (0°C) while saltwater freezes at a lower temperature depending on salinity levels, typically around 28.4°F (-2°C).
    Ice composition:
    When saltwater freezes, the ice crystals primarily consist of freshwater with the salt being excluded, resulting in a "brine" solution left behind.
    Density:
    Saltwater is denser than freshwater, which means freshwater ice will float higher in saltwater than in freshwater.
