Because of a phenomenon called "freezing point depression." Dissolving any solute in a solvent causes that solvent to freeze at a lower temperature than it would if it were pure (it also causes the boiling point to go UP). The salt in saltwater causes this effect. The amount the freezing point changes depends on the amount of dissolved salt.

Does freshwater marsh freeze faster than salt water marsh?
Freshwater marshes typically freeze faster than saltwater marshes due to the lower freezing point of freshwater compared to saltwater. Saltwater marshes have a lower freezing point due to the presence of dissolved salts, which can inhibit the formation of ice.
Does saltwater cool faster than freshwater?
No
Does saltwater evaporate faster than freshwater?
Yes
Why do freshwater boils faster than saltwater?
Freshwater boils faster than saltwater because salt increases the boiling point of water. The presence of salt in saltwater requires more energy to reach the boiling point compared to freshwater, causing freshwater to boil faster.
Which will freeze at a higher temperature of freshwater marsh or saltwater marsh?
Saltwater marshes will generally freeze at a higher temperature than freshwater marshes. This is due to the presence of salt in the water, which lowers the freezing point through a process known as freezing point depression. As a result, saltwater needs to reach a lower temperature to freeze compared to freshwater, which typically freezes at 0 degrees Celsius (32 degrees Fahrenheit). Thus, freshwater marshes are more likely to freeze at higher temperatures than saltwater marshes.
Does vinegar freeze faster than saltwater?
Hot water will freeze faster than vinegar because the hot water atoms will slow quickly and the vinegar will take longer to freeze because it contains an oil like sustance which take lionger to freeze.
Does iron rust faster in vinegar saltwater or freshwater?
Zinc will corrode in vinegar faster than salt water
Why do coins rust faster in saltwater than in freshwater?
Because salt is a corrosive chemical.
What is the variable of which water boils faster saltwater or freshwater?
Saltwater boils at a higher temperature than freshwater due to the presence of dissolved salts, which elevate the boiling point. This phenomenon is known as boiling point elevation. Consequently, while it may take longer for saltwater to reach its boiling point, once boiling, it can sustain higher temperatures than freshwater. Thus, in practical cooking scenarios, freshwater will reach its boiling point faster than saltwater.
Can saltwater and freshwater freeze different or the same?
Salt water needs to be much colder than fresh water to freeze because salt melts ice.
Why will an egg float in saltwater other than freshwater?
cuz saltwater is more dense than freshwater
Which is heavier saltwater or freshwater?
Saltwater is heavier because saltwater contains salt which adds to its overall weight. Freshwater does not have any dissolved salt so it is lighter then saltwater
