Hi,
What is the maximum or minimum level of salt that can be added to an ice mixture to reach a temperature below 0ÂșC but without freezing?
P.S.:Excuses about me poor level of U.K. English language...

Adding any salt to water will lower the freezing point.
I think this page might help.

A mixture of 23.3 grams of salt and 76.7 grams of water will freeze at -21.2 degrees Celcius.
That is as cold as any mixture of salt and water can get and stay liquid.
