What else can I help you with?
When seawater freezes what does the salt do.?
When seawater freezes, the salt is expelled from the ice crystal structure, resulting in ice being formed with very low salt content. The expelled salt forms a concentrated brine solution, which can affect the surrounding seawater density and circulation patterns in the ocean.
Would you expect the seawater just below the floating ice in the Arctic Ocean to be higher or lower in salinity then the water in the deep zone there?
When ocean water freezes into sea ice, some of the salt is incorporated into the new ice. Thereafter, that salt drains as brine (salt plus water), causing the layer of water below to be of higher salinity.
Can salt dissolve in freezing water?
Indeed this is a natural process. The salt crystals are of a different shape and density to those of water ice, and thus the salt will not be incorporated in sea water freezing. In the Antarctic, this salt is redeposited into the sea water, thus making it hyper-saline as well as dense. AND the sea water into which it becomes dissolved, becomes much colder than the remainder of the seawater, because the salt dispelled from the surface ice will be much colder than the bulk seawater. This then forms a hyper-saline current that is an important driver of oceanic mixing, and climate control.
Why does ice burg not melt with salt water all around?
Icebergs are made up of freshwater ice, which has a lower freezing point than seawater. The salt in the seawater reduces its freezing point, making it harder for the icebergs to melt. In addition, the dense, cold freshwater from the iceberg forms a protective layer around it, insulating it from the warmer seawater.
Why does the meeting of the ice caps lower the concentration of salt in the ocean?
When ice caps melt, fresh water from the ice flows into the ocean, diluting the salt concentration. This influx of fresh water reduces the overall salinity of the surrounding seawater. Additionally, the melting of ice caps can disrupt ocean currents and circulation patterns, further affecting the distribution and concentration of salt in the ocean.
When sea ice forms salt it is not incorporated into the ice crystals what happens to the salt?
About 80% of the salt is initially not incorporated, and that 80% just drains back into the ocean.

How does the salinity of sea ice compare to the salinity of normal seawater?
Ice has zero salinity. When it is frozen, the salt is pushed out. Therefore, since the salinity of normal seawater is about 35 ppt, it has 35 ppt more salinity than seawater.
Why does the melting of the ice caps lower the concentration of salt in the ocean?
The ice caps are made of freshwater.

Why doesn't the salt in the sea melt the ice in the arctic?
Salt only lowers the freezing point a few degrees, and this does initially slow ice growth. But once ice forms, most salt is either not incorporated or drains out eventually, so its influence is minimal.
How does freezing desalination work to produce fresh water from seawater?
Freezing desalination works by freezing seawater and separating the ice crystals from the remaining saltwater. The ice crystals are then melted to produce fresh water, while the saltwater is left behind. This process helps remove salt and impurities from seawater, resulting in fresh water that is safe for consumption.
Why does the meeting of the ice caps lower the concentration of salt in the ocean?
When ice caps melt, fresh water from the ice flows into the ocean, diluting the salt concentration. This influx of fresh water reduces the overall salinity of the surrounding seawater. Additionally, the melting of ice caps can disrupt ocean currents and circulation patterns, further affecting the distribution and concentration of salt in the ocean.
Went charter fishing in gulf of Mexico and had drinks in cooler with ice and they froze Why?
Likely some seawater got in with the ice, or the ice was made from seawater. Either way, the salt lowered the melting point of the water. Seawater has a salinity of between 3.1% and 3.8%. The melting point of 3.5% salinity sea water is -2 deg C, or 28.4 deg F. This could be low enough to freeze the drinks.
What is the seawater ice that forms a wide belt around Antarctica in the winter?
The name for the seawater ice, that essentially doubles the size of the continent, is called sea ice.
