Is rock salt adding on ice a mixture or solution?
A mixture. There are two definite phases
Why ice don't melt in table salt?
It is because when you put in table salt, actually any salt, the ice absorbs the salt's energy and that is what make the ice colder than it was.
When you make ice cream do you add salt to the ice or to the ice ingredients?
You add it to the ice used for cooling the mixture. It makes it colder. You don't want salt in what you eat!
Why do you use rock salt in ice-cream?
You don't use rock salt in ice cream, unless you want salty ice cream. You use rock salt (though table salt or sea salt would work just about as well) in the freezer to get it colder than you could with a mixture of ice and water.
What substance melts ice most efficiently sugar salt pepper or artificial sweetener?
== == Salt lowers the freezing point of water by 32 degrees. If salt is sprinkled onto ice, it causes the ice to melt by a heat transfer. Out of the substances listed, salt would melt ice most efficiently.
Why salted ice stays longer?
Salted ice does not stay longer. Salted ice melts sooner than ice alone because the mixture of salt and water lowers the freezing point of water. So the salt-ice mixture will melt at temperatures where pure ice would freeze. The only way that a salt-ice mixture would stay longer is if the temperature is so low that it has reached the freezing point of the salt-ice mixture.
Why do you need salt on the ice when you can use ice cream maker to make ice cream?
"The salt makes the ice melt. the melting of ice requires input of heat and this 'sucks' the heat out of the ice cream mixture causing that to freeze." You are correct. The salt lowers the freezing point of saltwater-ice mixture causing melting of the ice. Melting of ice is a process that absorbs heat due to the heat of fusion (80 cal/g of melting ice). Thermal energy is transferred from warmer (ice cream) to colder substance (ice/saltwater mixture). In this instance, heat is lost from the ice cream and transferred to the colder ice/salt-water mixture, allowing ice cream to freeze.
Is ice a pure mixture?
If there is no salt or substance that makes it impure it is a pure mixture

Why does salt ice melt faster?
The salt-ice mixture melts faster because the mixture's melting point is lower than that of pure ice, which is characteristic of a mixture. So the mixture causes the ice to melt at lower temperatures than 0 oC or 32 oF.
Why ice don't melt in table salt?
It is because when you put in table salt, actually any salt, the ice absorbs the salt's energy and that is what make the ice colder than it was.
How do you perform energy transfers?
A simple way to illustrate energy transfer is to put an ice cube in a glass of water. The heat energy from the water will transfer to the ice cube until thermal equilibrium.
What salt do you need for a ice cream maker?
Rock salt is cheapest, table salt works just as good. These will cool the salt and ice to about 10F. There are other salts that will get the salt and ice mixture colder, but they are generally more expensive and harder to get in quantity. If you want to experiment (and will be very very careful never to accidentally contaminate the ice cream mixture) you could test some of the "Ice Melter" products used on sidewalks in winter, some of these should cool the salt and ice somewhat below 0F. But these could be toxic!
Why is salt used in the preparation of ice cream?
Ice cream makers that consist of a container enclosed in a larger bucket of chunks of ice include salt with that ice because the salt lowers the temperature of the entire mixture. The salt causes the ice to melt, creating a drop in the temperature of the resulting icy salt water.
Why is salt added to ice when you're making homemade ice cream in an ice cream freezer.?
Salt acts as an antifreeze, reducing the melting/freezing point of the ice. This makes the salt & ice freezing mixture much colder than that of ordinary ice, causing the ice cream to freeze faster and with smaller crystals. An ice cream with smaller crystals feels smoother and creamier in the mouth.I use a compressor ice cream maker, which requires no salt & ice mixture as it has a built in electric powered freezer.
