# Salt: Relationships

Source page: https://www.materialinsights.org/commodities/salt/links/

Every element and industry that Salt is linked to, and how. Each pair has its own card explaining the relationships between the two.

- [Caustic soda](https://www.materialinsights.org/links/caustic-soda-and-salt/): Caustic soda is made by passing electricity through salt brine, so each tonne needs roughly one and a half tonnes of salt, but salt is cheap and power is not. The link that matters is physical and geographic: salt quality for membrane cells and access to coastal salt, which is why India's chlor-alkali industry clusters in Gujarat. *(researched)*
- [Chlorine](https://www.materialinsights.org/links/chlorine-and-salt/): Almost all chlorine is made from salt: electrolysing brine yields chlorine together with caustic soda, using about 1.65 tonnes of salt per tonne of chlorine in theory. Chlor-alkali makers are India's major industrial salt users, yet salt prices hardly affect chlorine, because salt is cheap and power is the main cost. *(researched)*
