How is salt able to melt ice?
That's good to know. So why is salt often used to melt ice on roads and sidewalks?
One reason is that salt is abundant and relatively cheap compared to other cryoprotectants. Additionally, the salty water that is created by the melting ice helps to decrease the freezing point of any additional ice that may form, leading to cleaner and safer roads and sidewalks.
