Why Does Salt Melt Ice Faster
I believe the salt melts the ice because of the molecules in the ice esacape into the water and the molecules of water is captured on the surface of the ice. Once the ice and the water reach the freezing point they coexist.Adding salt to the system will disrupt the equilibrium. I think the salt molecules will disolve into the water with out changing the chemical potential of the ice.
Get the ice and sprinkle some salt on it
Then get some some more ice (dont put any salt)
Collect data on which melts the fastest
The ice with the salt will melt the fastest
