Yes, it will keep the soda cold because the salt help the ice not to melt. Don't believe me check it yourself. Get an ice cube put a little salt on it and it doest melt. Or get an ice cube put some salt on it and then get a string put on top and IT WILL STICK!!!!!!!
how does salt help roads not freeze
The water would have to be colder than the ice to keep it cold. That is not possible unless it is brine(salt water). Then ice at 32f could be cooled by brine at say 30f.
No, but it can help soothe a sore throat if you gargle with warm salt water. See the related question below for more information on treating a cold.
Most probably , it would be fresh water. This is because since there is no salt which would keep the cold , the fresh water would melt faster.
The cold water becomes salt water. The salt doesn't dissolve like sugar.
Cold water is more dense.
The freezing point of water is lowered because by dissolution salt release heat.
normal water with salt
Cold water simply slows down the rate at which salt dissolves.
Since the salt makes water boil, get colder, and melt faster, salt water would be warmer in the summer and colder in the winter, but the salt would help, but not 100%, keep the water from freezing.
the salt prevents the water from getting cold
Same as the cold salt water.
