The reason why salt melts ice cream is the same as why it reduces the freezing lvl of water. It simply reacts with the ice seeing as the ice then gets a lower freezing point, the ice cream melts.
Rock salt is used because it causes the ice in the bucket to melt, but at the same time to be cold enough to freeze the ice cream inside of the canister. I am of course talking about the hand churned ice cream. If you didn't use salt, you would not be able to turn the canister to churn the ice cream mixture into a freezable substance.
Ice melt is made up of chemicals that are intended to melt ice. These chemicals often include salt as well.
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.
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.
You need to have the salt in the ice around the chamber to ensure that the ice will stay as frozen as possible when freezing the ice cream. ;)
Salt melts ice so salt will melt ice cream.
no
salt
Salt lowers the freezing point of ice so when the temp. outside is lower then 32 degrees, the ice will still melt. When making ice cream, when the temp. is lowered, the energy given off is transfered to the ice cream making it freeze.
no, but ice melt is a salt
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.
For making the ice colder? It wouldn't work at all. The reason you put the salt on the ice is to make it melt; when ice melts it absorbs heat. Sugar won't melt ice.
ice cream melts in the sun because when the heat of the sun get to the ice cream its starts to melt like ice.
You can eat rock salt but it is in a crude form. It won't hurt you and is generally used to make ice cream and to melt ice on sidewalks.
Fresh-water ice will melt faster in salt water than it will in fresh water or in the open air. Ice forms when water molecules are cooled down enough to arrange into solid crystals. Salt will, basically, get between the water molecules and make it harder for them to form crystals.
Ice cream will melt faster than yogurt, as yogurt does not melt.
No. Rock salt is used to make ice cream and melt ice on roads. Regular salt is not good for blood pressure because it will raise it.
