Does Adding Salt To Water Affect It's Freezing Point?
How does adding salt to water affect it's freezing point?

Pure water freezes at 0 degrees Celsius and 32 degrees Fahrenheit according to many sources such as www.iapws.org. According to www.blog.science-matters.org, adding salt to water does lower the freezing point of water.

If I add salt to water, then it will lower the temperature that it would normally freeze at.

The freezing point is the dependent variable, independent variable is the amount of salt, and the controlled variable is the water.

First, I got two equal cups of water. In the first cup, I put about 2 teaspoons in the water and stirred. In the second cup, I didn't add anything. I placed them both in the freezer for 90 minutes.

When I came back to check on them, the one

    But, a mixture of 20% NaCl and liquid water will have a lower freezing point (2 degrees Fahrenheit) than a mixture of 10% NaCl and liquid water (4). The 20% solution will then melt the ice much faster (though it isn't practical)(4). The material that melts ice the fastest is the material that dissolves into the greatest number of particles in a solution of that material and liquid water(4). It is important to learn how fast ice melts in different liquids because the Earth is currently going through global. If someone was able to find a way to keep ice from melting then maybe they could find a way to keep the polar ice caps from melting. Which could keep various animals from going extinct.If I place the ice in each liquid when they are at room temperature then I think the ice will melt fastest in the saltwater. When I first thought about which liquid would melt the ice the fastest I originally thought it would be the Pepsi because of the carbonation. But when I did research I found that the saltwater actually melted the ice melt the fastest. Which is one of the main reasons salt is put down on the ground when there is snow or ice on the…

    A solution’s freezing point depression is a type of colligative property. There are four types of colligative properties: vapor pressure, freezing point depression, melting-point elevation, and osmotic pressure. When a non-volatile (does not vaporize) solute mixes with the solvent, it lowers the vapor pressure of the solvent. This also raises the boiling point and lowers the freezing point.…

    On the countries where snow is abundant or have winter seasons they use salt to melt the snow or ice on the roads, and other areas. When making ice cream in a traditional hand-cranked ice cream maker (an ice cream maker that doesn’t use electricity, and just requires salt and ice and a bit of manual work), you pour salt on the ice surrounding the inner container. Doesn’t the salt melt the ice, why did the people place salt on ice?…

    In order to melt ice, deicers lower the freezing point so that the ice melts at lower temperatures. CaCl2 has a freezing point depression of 5°C, whereas NaCl has only a 3°C depression, and ethylene glycol, 1.85°C. The more the freezing point can be lowered, the faster the ice will melt, and more effectively. The reason to look at this is due to the fact…

    Salt melts ice mainly because adding salt lowers the freezing point of the water. Pure water freezes at 32°F (0°C). Water with salt (or any other substance in it) will freeze at some lower temperature. The normal freezing point of water is 0 degrees Celsius, so if the temperature is above that then ice will melt.…

    To find out how ice turns into water, to ice, people have to figure out it’s freezing point (the temperature which an object turns into a liquid, or solid). Water’s freezing point is usually about zero degrees Celsius. Ice’s temperature is in the negatives, so increasing the temperature to a positive amount of degrees of Celsius would be a good idea. But instead…
