To melt it, usually on sidewalks in the winter months.
Yes, the salt on popcorn is common table salt, which can be used to melt ice.
Salt is not used for making ice, because all you have to do to make ice is freeze water.
I believe that Morton Ice Cream Salt is just standard rock salt, used in making homemade ice cream.
Instantly, the ice is already melted. If the ice weren't melted, it would depend on what salt was used and the temperature of the salt and the ice. Certain salts, like magnesium chloride, melt ice much faster and at a lower temperature than table salt. If the ice is really cold it won't melt, regardless of what salt is used.
No just 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.
All over the ice is when they need to melt the ice. So they would get alot of salt and pour it all over the ground or road.
This depends on the type of water used to make ice.
Mixing salt with ice accelerates the melting of ice causing an endothermic solution gathering heat from the environment. It lowers the temperature. Ten pounds of ice and ten pounds of salt was used by Fahrenheit to arrive at the temperature now used as zero degrees Fahrenheit.
You add it to the ice used for cooling the mixture. It makes it colder. You don't want salt in what you eat!
No, salt does not stop ice from melting. In fact if the temperature is not too low it will cause ice to melt.
for melting ice on roads and sidewalks.
