Real table salt is never to be used as an ice melter on streets. “Salt” here is used in the chemical definition I would think.

The UK uses 2 million tonnes of rock salt a year for road gritting, which is basically dirty table salt.

https://en.wikipedia.org/wiki/Salt_Belt It's still a mix often times but it's totally salt in some areas still.

There is a salt mine up the road from me. The trucks start lining up for miles waiting for loads any time there is a winter storm expected.

The only difference between that salt and table salt is that there is additional processing to the salt done when destined for table salt to ensure purity and shape. So, yes, they don't literally use table salt, but it is the same raw ingredient.

Rock salt / sodium chloride is absolutely used as everyone is pointing out.

Liquid sodium chloride is also used in some places.

Neither of those are magnesium chloride and the distinction is important imo.

Liguid sodium chloride? Melting point is 1000C so I doubt that.

Allow me to introduce to you solutions.

For a practical experiment… add salt to water. You’ve made a brine. That is all.

>>SV_Bub+bv
Well, yeah, but I've never heard anyone call that "liquid sodium chloride"

I know of a company importing salt here in Norway. They get boats filled with salt, and when doing the import customs declaration they have to decide if that batch of salt is going on the dinner table or on the roads, because we have half VAT on food and ingredients.

Same salt, different VAT rate depending on use.
