Why is salt used to melt ice?
Salt is usually sprinkled over snow covered roads during winter. But how does it work?
Salt and water mix is what is called an eutectic system.
In this type of mixture both ingredients have higher melting temperatures than respective individual components. To make it simple: Apparently the crystal structure that characterizes eutectic components is destabilzed by the addition/mixture of a second component, thus lowering the melting point. And the melting point is when crystal structure is dissolved.
Salt melts ice essentially because adding salt lowers the freezing point of the water.
