Companies are experimenting with replacing sodium chloride with potassium chloride, because most of the health problems come from sodium. It works for some products, but if you diminish the amount of sodium, people want sugar and fat instead.

Whereas, generally speaking, zinc reacts suitably only with the first members of the alkyl iodides, with magnesium it is possible to use bromides, iodides, and in many cases, chlorides.

French Scientist

Chloride is found in everyday substances like salt.

Common Compound

Some chlorides are vital for health, others can be toxic.

Health-Relevant

Despite 'salt' synonym, not all chlorides taste salty.

Not Always Salty

Chloride specifically refers to chlorine ions with a negative charge.

Ion Specific

Chloride ions are crucial in cellular functions and fluids.

Biological Roles

Chloride can reveal pH levels when used in chemical tests.

Acidity Indicator

Chloride-based products are used for everyday practical purposes.

Practical Uses

Some chlorides are used in food preservation or preparation.

 and that's what that image on the left is -- gradually getting encrusted with the calcium carbonate. So after a while, we could take that out, use it as a lightweight building block. And if you think about the carbon in that, that would have come out of the atmosphere, into the sea and then locked away in a building product. The next thing is sodium chloride.

 So I brought my two biochemistry friends and we went to talk to him about our crazy theory. And that theory was that life produces all small molecules, so many molecules.
