What is Rock Salt?

Rock Salt also known as Road Salt is a mineral called Halite which is formed from sodium chloride.

Rock Salt is the industrial name which is more relatable to the general public. Rock Salt is usually colourless or white. However, the colours can change depending on the amount and type of impurities contained within it changing it to a brownish colour.

The primary difference between Rock Salt and ordinary table salt is the size and colour. Rock Salt forms in very large, chunky crystals, unlike small crystals seen in table salt. Similar to table salt, Rock Salt also has an assortment of minerals which can have an impact on how it behaves chemically. The large crystal size of Rock Salt means it is not usually used in cooking as it takes too long to dissolve. 

Why do we use it?

When cold weather arrives, stores stock up on big bags of Rock Salt and you may see lorries spray it on the roads or it being shovelled on the pavements. This is to melt the ice for vehicles and pedestrians to be safe when out and about in the wintry conditions.

How does it work?

The salt breaks down into the liquid part of ice, the added particles make it more difficult for the water to freeze into ice, lowering the freezing point of the water. For Rock Salt to work, there needs to be a tiny bit of liquid water. Rock Salt is not effective in extremely cold weather when water would freeze too easily.
