In simplicity, salt decreases the freezing temperature of water by allowing the particles of water (H2O) to more faster at lower temperatures. By giving this answer, I assumed you are familiar with the particle theory and the Periodic Table of elements.

Will a temperature of a beaker of water increase or decrease when its mixed with salt?
This is the typr of experiment that is performed with a 'Slurry' of ice and water in the beaker, and not just room temperature water. Adding salt to a slurry will cause some of the ice to melt. When ice melts, the temperature of the solution will drop, and potentially below the freezing point of pure water.If the water and salt are at room temperature, the mixing will yield no significant changes in temperature.
How much salt is needed to stop 100ml of water freezing?
Salt lowers the freezing point of water. To prevent 100ml of water from freezing, you need to add approximately 6-7 grams of salt.
What is the temperature if you put salt in water?
Adding salt to water lowers the freezing point of the water, meaning it will freeze at a lower temperature than pure water. The exact temperature will depend on the concentration of salt in the water.
How long does it take for salt water to melt?
The time it takes for salt water to melt depends on various factors such as the temperature of the salt water and the amount of salt dissolved in it. Salt water typically has a lower freezing point than fresh water, so it will begin to melt once it reaches a temperature above its freezing point. This can happen relatively quickly if placed in a warm environment, such as room temperature.
Does salt water expand when it freezes?
Yes, salt water expands when it freezes. The salt decreases the water's freezing point, so it remains a liquid at a lower temperature than freshwater. As it starts to freeze, the saltwater becomes more concentrated, leading to an increase in volume and expansion.

How does salt keep water from freezing on your roadways?
Salt lowers the freezing temperature of water, which means that it has to be colder for the water to freeze.
What is the reaction of salt in the water at freezing temperature?
Salt doesn't react with water.
Does salt affest the freezing point of water and why?
The addition of salt to water will affect the freezing point as it the freezing point temperature is lowered. It's not the salt that lowers the temperature but it's because a new solution that was created.
How does salt cause the snow to melt?
Ice forms when the­ temperature of water reaches 0 degrees Celsius. When you add salt, that temperature drops. Addition of salt makes makes the melting point of ice increase, making the freezing point of water a lower temperature than just water along (i.e. without addition of salt). The salt dissolves into the liquid water in the ice and lowers its freezing point.
How does the salt melt the snow?
Ice forms when the­ temperature of water reaches 0 degrees Celsius. When you add salt, that temperature drops. Addition of salt makes makes the melting point of ice increase, making the freezing point of water a lower temperature than just water along (i.e. without addition of salt). The salt dissolves into the liquid water in the ice and lowers its freezing point.
Why does salt effect the freezing point of water?
Salt mixes with the water raising it's freezing temperature above normal.
Why does the Arctic Ocean freeze and the Pacific does not?
As water freezes salt is released increasing the percentage of salt in the ocean water, the higher the percentage of salt the lower the freezing temperature of the water. The cycle of water freezing -> salt being released -> more water freezing reaches equilibrium at witch point the temperature necessary to freeze more water is lower then the air temperature.
Why does melt ice the fastest?
salt water freezing temperatureWhen you place salt on the ice it starts to disolve making a saltwater solution .Salt water has a lower freezing point than water; therefore, the ice melts until the temperature of the water reaches the freezing temperature of salt water at that particular concentration.
If you add salt to water does it make the water hot or cold?
salt doesn't change the temperature of water, it changes the freezing point. salt lowers the freezing point of water so that it will become ice at a lower temperature, therefor melt at a lower temperature which is why salt is put on the roads when it is icy
What is a freezing point depression?
Freezing point depression is when the normal freezing temperature of a liquid is lowered by the addition of another solate for example the freezing temperature of fresh water can be lowered by the introduction of salt. This is why when salt is laid over snow the snow melts because the salt combines with the water in the snow and thereby increases it's freezing temperature.
Why does the freezing point affect the freezing of salt water?
Salt water has a lower freezing point than pure water because the presence of dissolved salt interferes with the formation of ice crystals. When the temperature drops below the freezing point of salt water, the salt ions prevent water molecules from arranging into a solid crystalline structure, requiring a lower temperature to freeze.
